Sol runs to the hospital and sees Sun Jae’s father anxiously waiting outside the theater. She decides to find the watch and go back in time to change what happens so she goes to Sun Jae’s apartment and starts crazily rummaging through his things. She then sees In hyuk who is surprised to see her. She asks of Sun Jae’s old watch so she could save him but he tells her Sun Jae lost it. He berates Sol, yelling that she’s the reason why Kim came for Sun Jae.
Sol is confused and gets the report of what happened in 2008 from Tae Sung’s father. Turns out, this is a different event from the one she just experienced. Sun Jae had found Sol at a warehouse. She just escaped from her kidnapper and fainted upon seeing him. However, Kim Young Soo spotted Sun Jae and tried to escape from him but he caught him and they both fought until Sun Jae smashed his head with a brick and he got arrested.
At her home, Sol in a maddening state, begins to search through the police documents for any sign of the watch when she suddenly spots a picture of the watch on one of them. She calls Tae Sung’s father to ask if the victims belongings are still in the police station but he tells her that they are returned to them. Sol concludes that her past self must have had the watch and kept it somewhere in her house. She searches everywhere but surprisingly finds it on her grandmother’s wrist. Her grandmother tells her she kept it well for her. (Okay. That’s weird. I think the grandmother later knew she was time traveling)
Sol happily takes the watch. Later she visits Sun Jae who is in a critical condition at the hospital. She’s determined to save him this time but resolves not to get near him so he wouldn’t have to risk his life because of her. As soon as it strikes twelve, Sol presses the button and goes back in time. When she opens her eyes, she finds herself seated on top of a horse statue. It’s the year 2009 and she’s now in college. People stare at her murmuring how she managed to get herself so high up there. She loses her balance and falls thinking she would die but the last person she expected saves her and that’s Sun Jae. She’s shocked as she finds herself in his arms but without saying anything to him, she runs away in a state of panic.
Hyun ju who had witnessed the scene follows her, asking why she didn’t thank Sun Jae for saving her life but Hyun ju replies that the best thing for him would be if she stayed away from him. She asks why Sun Jae is attending the same university as her and Hyeju replies it’s because he’s now studying physical education which doesn’t seem right to Sol because Sun Jae debuted in Eclipse and didn’t attend college. Hyun ju hands her a paper bag containing her uniform and she hurries off to the police to report Mr Kim before he does anything. She even gives them the key to his taxi as evidence and claims he is the one responsible for the unknown murder at the reservoir. As she leaves the station, she suddenly spots a man seemingly trying to bully money from a college student.
Sol decides to help the boy but ends up recognizing the ‘bully’ as Tae Seong. Sol misunderstands him when he had actually helped the kid find his money. The boy thanks him and runs away. Sol and Tae Sung catch up inside a cafe. She still thinks he lives a rowdy lifestyle but he surprises her when he tells her he actually graduated and even owns an online fashion store. He is doing pretty well now and thinks Sol is trying to gain his attention again. Sol is just amused at him. After sometime, he stands up to leave but tells her she really succeeded in grabbing his attention.
Meanwhile, Sun Jae is at In hyuk’s place, wondering why Sol ran from him the moment she saw him as if he were a ghost. He tells In hyuk that she acted differently this time and even got red in the face when they met but In hyuk tells him she ran because she hates him. He tells him she must have felt uncomfortable because the guy she dumped ended up going to the same university as her and can’t seem to move on. Sun Jae isn’t happy to hear that. In hyuk notices Sun Jae is writing a song and thinks it’s because of Sol due to how sad the lyric is but he denies it. In hyuk invites him to join their band and replace their terrible vocalist.
Sol arrives home but avoids running into Sun Jae. At home, Sun Jae’s father tells him he could still go abroad to treat his injured arm. Sun Jae promises to think it over. However, he is still saddened over Sol’s rejection as he looks at the song he had written because of her.
Tae Seong drops off underwear for his father at the police station but he had mistakenly taken Sol’s bag so what they saw was her university uniform. Meanwhile, Hyun ju wakes Sol up to remind her of their orientation that day. Sol had gotten a text from the police that her case has been transferred to the violent crimes section and investigation is underway. Sol is happy that she’s been taken seriously. Meanwhile, Hyeju checks out the paper bag she had given her and both girls scream when they see male underwear inside.
Tae Sung’s father receives Sol’s report and his partner suggests they check out the location she had given them and see if it’s really Kim Young Soo’s hideout.
On their way to the orientation site, Sol is uncomfortable when she finds out she’s on the same bus with Sun Jae. She quickly hides in order to avoid him. Inside the bus, a student suddenly talks about a myth surrounding the field they were going to. It was believed that anyone who kissed in the field during the first field trip for new students would end up getting married. Two students kissed there and got married. Even two male students who had kissed due to a dare ended up traveling abroad and getting married ten years later. Everyone is stunned.
At the camping site, Sun Jae immediately notices Sol wondering how he didn’t even see her in the bus. Geum, who is an older student, sees him and warns him to keep his lips away from his sister, telling him he is completely eliminated from his list of potential in-laws. Throughout, Sol tries not to let her presence known but in the end one of her seniors whom she kept running into that day notices her and forces her to play a game. If she lost, she would have to drink and then dance in front of the physical education students. Sol unfortunately loses so she is forced to dance in front of the physical education students, relieved when she doesn’t see Sun Jae but turns out he was just lying down at the back. He raises up and sees her. The moment she sees him, Sol runs away in embarrassment. The senior who won laughs at her, thereby irritating Sun Jae.
The senior follows Sol and tells her to continue her punishment but she yells at him in anger and even breaks a wooden cup on his head. She leaves but immediately she sees Sun Jae outside, she hides, mistakenly running into boar territory.
Meanwhile, In hyuk and the other eclipse members are tired of their vocalist’s inconsistency and decide to enter a music competition in order to become more well known.
Sol gets afraid in the forest. She tries to find a way out but panics when a hand touches her shoulder. She hits the person with a taser. However, she’s surprised that the person is Sun Jae. He seems to have collapsed. She is scared because she has no network to call for help but Sun Jae wakes up, seemingly alright. Sol tries to run away from him but she ends up in an animal trap. He holds her tightly in order to free her. When she’s free, he asks what she says doing at the boar trail and she lies that she was tired of the trip but Sun Jae knows it’s a lie and accuses her of trying to avoid him all day. He tells her she doesn’t have to act this way with him. The atmosphere between them is awkward and he decides to lead her back to the camp.
Geum sees them and suspects they did something in the forest but Sol doesn’t even say anything and walks away. Geum holds Sun Jae back from leaving and starts giving him advice on how to get a woman to fall for him by not acting clingy but he goes against himself when he borrows Sun Jae’s phone to call his girlfriend who had dumped him.
Meanwhile, Sol is drowning herself in alcohol refusing to interact with her friends. Her brother is the same as well, crying over his ex. In his drunken state, he shouts that he would see her. He then leaves and Sun Jae goes after him but loses track of him. However, Hyun ju who is outside to get drinks sees Geum and follows him.
Sun Jae is still searching for Geum when he sees the senior who had humiliated Sol. He is all dressed up carrying flowers. He shouts in front of the girls lodge calling the girl he likes to come out so he can confess to her. But he has a running stomach and rushes to the public toilet to release himself. However, the door to the toilet is loose so he asks Sun Jae to help him close it. But Sun Jae recognizes him as the one who humiliated Sol so he leaves the door open and the girl who he likes comes out with her friends to hear his confession only to see him pants down in the toilet taking a shit. (How embarrassing)
Sun Jae who is still searching for Geum suddenly sees Sol who is drunk in the field. She climbs on a tree house and lays down there full of regret.
Meanwhile, Just like his sister, Geum also ends up in the animal trap. Hyun ju sees him and tries to help. She gets happy when she hears him crying over his break up but when he starts whining to get back with his ex, Hyun ju is unable to stand it and kisses him twice to stop him from talking. (Spiderman style type of kissing)
Sun Jae sees Sol is about to fall from the tree house so he rushes to her and stops her but when she sees him, she starts crying pleading with him to stay away from her. She calls him an idiot for still worrying about her even after she had rejected him. Sun Jae is just so confused by her behavior.
Later that night, Sun Jae goes to see In hyuk who suggests that he enter the band with his group so they can use his song in the competition. Sun Jae seems bothered about something and asks if he had ever told anyone else about the song but In hyuk tells him he told no one else.
Meanwhile, Tae Seong’s father and his partner check out the location Sol had given them but Kim Young Soo had already burned down the place, thereby destroying all evidence. The partner informs Sol the next day and she gets scared that Kim already knows she reported him and might soon come after her and Sun Jae.
As she’s leaving her house, she gets surprised to find Sun Jae waiting outside for her. He asks her how she knew his song when no one else has heard it except for In hyuk. He recalls last night while carrying her on his back, she had started humming his song which surprised Sun Jae. When he asks how she knew it, she drunkenly murmurs that she will change everything when she goes back. He asks where she’s going to and she replies she’s going to the future, to her time.
Now, Sun Jae demands to have an answer, asking if she’s going to her time, who she really is and if she came from the future? Sol is stunned
Epilogue
Back at the tree house, Sun Jae is trying to get Sol on his back but in the process, they mistakenly kiss.
(So they’ll marry in the future because according to the myth, anyone who kisses on the field would get married.)
