In the start of Episode 12, Gwi-ju finds out that his scar will be healed in one week, which makes him realize the limited time he has remaining. He encounters Da-hae at the pharmacy and they go out on a date.
At the same time, I-na attempts to convince Hye-rim to return to the dance club by joining her for lunch. Hye-rim, currently shunned by others, shows no interest. Grace brings in Hyung-tae to work as an extra gym trainer, in search of a new job following the failure of their original plan. Dong-hee recalls him as a delivery worker who always delivered her food intact and is immediately attracted to him, despite the fact that Hyung-tae was only working that job to keep an eye on her.
Grace is awkward standing between the two. But Hyung Tae suddenly feels as if they are been watched. It’s Ji Han and he tells himself he would destroy them all.
Afterwards, during her jog, Ji-han confronts Dong-hee and attempts to coerce her into marriage, but she declines. Upon her departure, Hyung-tae meets Jin han and intimidates him then he accidentally plunges his phone into a pond, causing the footage of Dong-hee and Grace to be lost.
Ms Bok frequently dreams of a fire and students waving in the air. She confides in Gwi-ju, who goes to see his old coworkers at the fire station and asks for the records of the fire accident from 13 years ago.
While at home, Gwi-ju displays strange behavior during dinner, leading Da-hae to inspect the scar on his neck as he sleeps. Gwi-ju comforts her by saying the scar will not disappear quickly, suggesting they have plenty of time to say their goodbyes. They hug each other tearfully.
As Gwi-ju hurries back to the location, Hye-rim eventually becomes a part of the dance team. I-na conquers her anxiety and her team achieves success with cheers and smiles. Following the performance, I-na notices Hye-rim departing and decides to follow her. I-na talks about her efforts to be close to Hye-rim, while Hye-rim admits she wished I-na would be more transparent. It becomes evident that Hye-rim had the same feelings for I-na as I-na had for her.
While sitting among the spectators, Da-hae notices Gwi-ju’s clothing and informs him that he had on the exact same outfit when he informed her about I-na’s disappearance. Gwi-ju departs unexpectedly, as Ms Bok identifies an acrobatic routine from her dreams and understands that the fire she witnessed will occur at the competition location.
Gwi-ju and Da-hae hug each other before Gwi-ju goes back in time. Soon-gu quickly rushes to activate the fire alarm when Ji-han inadvertently causes a fire in the green room. Da-hae’s family and the Bok family work together to clear people out of the auditorium, while Dong-hee uses her abilities to prevent the stage curtain from catching fire when the flames reach the backstage area. Both families are in awe by what she has done.
While Gwi-ju is in the past appearing sad, upon his return he finds the place in disorder and a loud fire alarm sounding. During Da-hae’s search for I-na, Gwi-ju is also searching for Da-hae. I-na and Hye-rim are stuck when the fire shutters block their sole way out. I-na goes behind the scenes to search for an exit. Gwi-ju locates Hye-rim, assists her, and tracks the same route as I-na.
Da-hae discovers I-na behind the stage, but I-na faints due to the smoke. Right before they are squashed by a wooden plank, Gwi-ju shows up. They come to the realization that it is time to say their farewells. Reluctantly, Da-hae goes with I-na, while Gwi-ju travels to the past as the wooden board crashes to the floor.
He goes back to when I-na was born and expresses gratitude to Se-yeon, who manages to glimpse his future self. After Gwi-ju exits the hospital room, his surroundings are filled with colors. Upon arriving at Da-hae’s school, he has a short encounter with Chief Jung, his firefighter colleague, before Jung perishes in a structure collapse. Gwi-ju retrieves firefighter equipment, locates Da-hae in the storeroom, and rescues her. He bids farewell to Da-hae as the school building collapses, then assists her onto the safety net before apparently succumbing to the flames.
In the current time, the Bok family gathers to mourn Gwi-ju, who has not been seen since the fire. Ji-han is incarcerated. After five years, Da-hae resides with the Bok family alongside their son, Nu-ri. I-na is currently a student in high school.
Dong-hee is the owner of a gym building and enjoys spending her time flying with Hyung-tae. Grace continues to struggle in her auditions and has not achieved success yet. Ms Bok frequently goes to Il-hong’s sauna and assists her in achieving her aspirations.
Somewhere else, during a play session with Nu-ri, Da-hae discovers that Nu-ri possesses the ability to summon objects from history. She inquires if he is able to bring back his father from 18 years in the past but he gets distracted. After Da-hae walks away, she notices Gwi-ju standing with Nu-ri, who had just rescued her younger self in high school. Tears of joy streaks down her face as she welcomes him back home.
It was a rather underwhelming finale with lots of things left unexplained. However, it was still a safe watch but if only they had added more episodes to further explain thing.
My rating: 7.5/10
