In the second episode, before she leaves, Su Yeon vows to slowly take back the life which Sun hui stole from her. Burdened, Sun hui writes a letter to Su Yeon as advised by her father, apologising for her mistake and promising to make up for it for the rest of her life.
The next morning, Su Yeon finds the letter under her locker. After reading it at a rooftop, she is touched by Sun hui’s sincerity. Just then, the two rouguish girls from before meet her to ask about her relationship with Su yeon. They also heard rumors that she wears a wig and are curious but Su yeon ends up beating them to a pulp and warning them to stay away from Sun hui.
However, that night, she is waylaid by the girls and their male friends who beat her until Gyeong ho suddenly appears and saves her, displaying great combative skills as he defends her against the boys. He even runs away with her to escape the police and Su Yeon is pleased when Gyeong ho and his friend escorts her home. When he leaves, she brings out the silver pendant she had taken from Sun hui and stares at it lovingly indicating that she has a crush on Gyeong ho.
In school the next day, Su Yeon joins Sun hui, Gyeong ho and his friend in taking pictures and then makes Gyeong ho take a picture with her even though he’s reluctant. That night, Su Yeon has dinner with Sun hui and her family, trying to disguise the sadness she really feels. As Su Yeon leaves, Sun hui’s father suggests that he would like to go on a trip with her and Su Yeon which makes Sun hui happy
At school the next day, Su Yeon gets angry when she overhears Gyeong ho telling his friend that he could never like her. The only one he would ever like is Sun hui even though she rejected him. He still plans to tell her his feelings once again. Su Yeon confronts Sun hui in class, threatening her not to meet with Gyeong ho or listen to anything he says or their friendship would end.
On their way out of school, Sun hui rejects Gyeong ho’s invitation to meet later, claiming that she has to study. Just as they reach Sun hui’s house, Su Yeon rejects her offer to eat dinner with her family that night and they part ways.
Then we are taken to the beginning of the series where Sun hui rushes out of her house to give Su Yeon her math homework only to see her entering Gyeong ho’s house. Upon meeting Gyeong ho, Su Yeon is jealous of the decorations he has made to confess to Sun hui. She criticizes it, causing Gyeong ho to misunderstand she may have feelings for Sun hui. Just then, outside, Sun hui hears Su Yeon scream and rushes inside only to see Su Yeon holding a knife and Gyeong ho restraining her.
She yells at Sun hui for coming regardless of her warning. She blames her for her problems and just as she’s about to stab her, Gyeong ho steps in and gets stabbed instead.
Later, we see Sun hui crying to her mother about killing Gyeong ho. She says there were no witnesses and wants to turn herself in but her mother surprisingly tells her she would take care of everything. She has her change clothes and the next morning, after waking up, Su Yeon is surprised that the math home work and her phone which she left behind at Gyeong ho’s house is lying on her table.
She goes out to see her parents, especially her mother acting like nothing happened. They don’t even budge when it’s announced in the news that Gyeong ho and his family died in a mysterious fire.
Meanwhile, two detectives go through Gyeong’s burnt family house theorizing that it’s surprising that everyone died in their sleep due to drunkenness and not one of them survived. One of the detectives spot Su Yeon outside the house with the crowd. She seems weird because of this, he decides to first question those close to Gyeong ho.
Su Yeon who has been calling Sun hui who has not been picking up runs over to her place. The episode ends with Sun hui feeling burdened as Su Yeon repeatedly calls her phone and her mother knocks on her door.
The epilogue shows little Sun hui meeting her adoptive parents for the first time at the orphanage.
So, the family is plain psychotic and Sun hui is just realising that because how did Gyeong ho’s family’s house get burnt and why did Sun hui insist she killed Gyeong ho when it was clearly her? More to find out about. Keep up with the recap. Thank you.
