Ou Yuna

Yuna is taken around at night by Onyu after he had exclaimed loudly that he loved her. Onyu explained his circumstances to her, and was keeping watch to know if they were being followed. Bringing her through the grounds of a university, they encounter a fence that Onyu breaks apart as he tells Yuna that he'll help her climb down. The two of them are confronted by Cuckoo, which Onyu fights off with a metal pipe. Cuckoo is confused by Onyu's serious intent to kill, considering all the incidents around Yuna's curse were never fatal. Cuckoo is eventually saved and taken away by Crow, after which Onyu is distraught because he was unable to change what the notebook said would happen.

At school, Yuna encounter the Park twins, and invites them to eat lunch with her at the rooftop. After that, she meets Onyu again, who is immediately met with a slap to the face as she tells him to not come near her.

After Shung's death in the alleyway, and Onyu being several injured, he returns them to 30 minutes prior. This allows them to be saved by Yuna's caretaker, and Onyu is taken to the hospital. The scene changes to one of Ji-Hyun Park talking to Onyu, seemingly at the place where young adult Onyu arrived when he went back in time. Ji-Hyun Park wants Onyu to do things right in order to end the cycle, saying that when he wakes up he will forget everything as per the results of the timeslip. Onyu wakes up in the hospital with Yuna at his side, but is ignorant of everything that has happened beforehand. Yuna is confused by this and begins thinking Onyu should just go back to the future. She still believes Shung will come back and wants to leave Onyu behind. They are confronted by Crow and Bustard, similar to what the notebook said would happen. As Onyu fights Rin, he is slashed across is left eye with something sharp. Bustard corners Yuna and tells her she must stay with him. She is saved by her caretaker and gets a chance to run away. We see her father-figure push Bustard down, holding up a knife as his sunglasses slip to reveal an eye color very similar to that of Onyu and Bustard.
