In the year 2013, Sol in her wheelchair listens to the radio where the host is congratulating Sun Jae for his first successful song which talks about his first love. She asks him to describe his first love and he tells her how he met his first love on a rainy day and she placed an umbrella over his head. Not knowing she’s the one being referred to, Sol wonders who Sun Jae’s first love could be.
Sun Jae hears that Sol is being harassed by Ga hyun, the girl who likes Tae Seong. He starts searching for her but can’t find her. Meanwhile, Sol beats Tae Seong up and breaks up with him after finding out that he had only dated her to get rid of Ga hyun. She warns him that if the real Sol comes back and she begs him to rekindle their relationship, he should refuse.
So she leaves in anger and that’s when Sun Jae sees her about to cross the road. He approaches her and asks her to break up with Tae Seong. Just then, she hears his voice in the recording telling her he likes her. Sol gets flustered and runs to the bus in order to avoid Sun Jae.
However, at home she’s unable to concentrate as she tries to understand how Sun Jae could possibly like her. Her grandma scolds her for not peeling the onions properly and sends her to buy Makgeolli, a local beer.
Meanwhile Tae Seong is talking to his friend. He doesn’t know why he felt hurt when Sol broke up with him. Sun Jae who is walking with In hyuk just then, overhears Tae Seong talking about going on a blind date. Thinking he’s cheating on Sol, he goes to fight with him but pauses when he hears that Sol dumped Tae Seong. He is suddenly glad and hugs Tae Seong who is surprised to see him.
He leaves everyone and gets in a great mood as he hurries to Sol’s house but he finds her crying. He approaches her, frustrated, thinking that she’s crying over Sun Jae. He then sees the Makgeolli in her hand and thinks she wants to drink away her sorrows. He starts dragging the bottle with her but Geum arrives and thinking Sun Jae wants to get Sol drunk, he gives him a flying kick to the jaw. (Haha…it’s hilarious)
While he lays on the ground,the drops from the falling Makgeolli end up in Sun jae’s mouth and he collapses.
Next, we see him in Geum’s room while Sol is worried about him knowing he passes out after a few sips of Makgeolli bit Geum just thinks he’s weak. When no one’s watching, Sol sneaks into the room to check on Sun Jae. Thinking the weather is hot, she brings a fan to cool him down, then checks to see if he’s breathing. While her hand is on his chest, Sun Jae unconsciously grabs it but she hides when she finds him waking up from sleep. Sun Jae is momentarily confused but then he notices Sol’s hair sticking out from under the bed. At first he’s scared but Sol immediately stops him from screaming and a moment passes as they stare at each other. But when they notice Geum is entering the room, Sun Jae covers her with the bed sheet. They try to hide but they are eventually caught. Sol runs off in embarrassment.
The next day, Sol speaks with Hyun ju about Sun Jae as she wonders how someone like him could have fallen for her. Hyun ju simply replies it was because she chased him around everywhere. There was no way he couldn’t have fallen. She advices her to focus on studying first. They both get to the study hall but Sun Jae coincidentally turns out to be Sol’s seat partner. They are both tense and Sun Jae tries to act cool after In hyuk advised him not to act desperate with Sol just because she recently broke up.
Meanwhile, Tae Seong is still unhappy with the break up and clings tightly to the Teddy bear Sol had gotten for him. Sol and Sun Jae are coming back from having dinner together. Sun Jae invites Sol to come with him to cheer on the national team’s base ball game but Sol, feeling she may be leading Sun Jae on, accepts on the condition that he memorizes the entire English text book, a seemingly impossible task but to her surprise, Sun Jae accepts the challenge. They suddenly run into Tae Seong who has come with the Teddy bear to plead with Sol. Despite the tension, Sun Jae allows them to speak but imagines them reconciling. Tae Seong admits to Sol that the only reason he accepted to be her boyfriend was because he must have liked her. Although he’s still quite confused about his feelings. Sol finds his confession ridiculous and struggles to take the teddy bear from him but in the process, they end up hearing a recording inside the teddy bear of Sol saying that she would love Tae Seong forever. Sol feels like dying from embarrassment.
Meanwhile, Sun Jae pretends to help his father in his garden but he is secretly waiting for Sol to come back home. He’s happy when he finally sees her but he ends up getting hit by his father for tending to the garden wrongly. Tae Seong gets into an accident while on his way back. The next morning, Sol’s mother tells her she’ll be going on a trip. Sol knows she’s going with her lover and recalls in the past when she was highly against her mother dating. But now, she thinks differently and tells her she and Geum would be able to live properly without her
Sol goes to the police station and tells the police officer to be watchful over her on September 1st, the day of her accident but the police officer sends her away thinking she’s delusional. Just then, Tae Seong’s father comes to ask for surveillance footage of the previous day..
The pervert speaks to grandma on the phone asking how to send Sol her phone. Grandma tells him she would send him their address. (I sense danger)
Sol goes to the study hall and finds Sun Jae asleep on his table. She gets mesmerized by his good looks bur struggles to regain her senses when she discovers what she’s doing. She falls asleep and wakes up to find Sun Jae staring at her. Awkwardness sets in and Sol rushes to the rest room to calm her neves but Sun Jae follows her and asks if she had already found out. Thinking he’s referring to his feelings, Sun Jae tells her he has memorized the whole English text book so she has no choice but to come with him to the base ball game.
The next day, Sol comes to the baseball game and she tries to stop herself from falling for Sun Jae as he does things that charms her. Meanwhile, Hyun ju is also trying not to fall for Geum as they are watching the baseball match but her efforts proves useless. She ends up suffering heartbreak when she learns that Geum has a girlfriend.
Tae Seong is in the hospital after his accident and his friend teases him because his parents don’t even care about him. Suddenly, they see Sun Jae and Sol cheering together on Tv. Tae Seong gets jealous and his friend teases him that Sol has moved on so fast. Tae Seong sends him out of his ward but in the process, notices Sol’s mother in the hospital.
Sun Jae is unable to hold back on his feelings and just seconds before their Korean baseball team wins, he drags Sol out of the stadium and confesses his feelings to her. He tells her that he had always hated the rain but that has changed because of her. Seeing her flustered state, he says he would give her time but the moment is interrupted by Tae Seong’s call. He tells him Sol’s mother is in the hospital. The two of them go there and discover her mother was due to have surgery because of a gastric disorder. The man she was frequently seen with was actually her doctor.
Sol feels so bad because before she left, she had told her mother she could live without her. Now, she regrets not knowing about her condition this whole time. Sun Jae sticks by her side. Later, Sol meets with Tae Seong to thank him for calling her. Seeing his state, she thinks he was in a fight but Tae Seong pouts that she thinks so lowly of him. She sees a boy in a wheel chair and it brings back memories. She advices Tae Seong to try and turn his fate around. It’s the least she can say to her first love.
Sun Jae returns to the hospital to see Sol but she coldly rejects his confession thinking that she led him on and that was why he developed feelings for her. Sun Jae tries to assure her it isn’t that but she sticks to her gun leaving him dejected. On her way, she recalls her conversation with Hyun ju who had asked her how she truly felt for Sun Jae but she had ignored it because she would leave soon but after what has happened, she realises her true feelings and hides in a corner to cry.
It’s the day of the accident. Sol refuses to go anywhere, even when her brother who is looking after their mother in the hospital calls her to get him his phone. But when Sun Jae sends her an email, telling her he had found her umbrella which was in the study hall, she falters. She sees Sun Jae from the window drop off her umbrella at the door before strolling away. It suddenly begins to rain and Sol gets concerned, thinking he was waiting for her. Despite herself, she rushes out and grabs the yellow umbrella Sun Jae had kept. Suddenly, a courier man passes her by and Sol finally remembers the first day she met Sun Jae on a rainy day. She recalls Sun jae’s words and realizes he has always liked her, not because she led him on. She starts running to meet him but freezes on the spot when a cab pulls up in front of her and Sol recognizes the driver. It was the man who had kidnapped her.
Meanwhile, Sun Jae is heading back home when the cab drives past him. For some reason, Sun Jae feels the cab is suspicious but he continues on his way. However, when he sees Sol’s umbrella on the ground, he knows something is wrong.
The episode ends.
