Fix everything before it's too late

Kim Hongjoong has a crush on Seonghwa. Its obvious. The staff, the fans, his friends, and even the other members know other than Seonghwa himself. Hongjoong loves everything about the oldest member. Despite having a past where he's scared of being rejected, he confesses and Seonghwa accepts it but the new couple faces a challenge in their relationship....Kwon Nari.

Kwon Nari, a model and the spoiled daughter of the CEO of a modeling company was the former fling of Seonghwa. The reason he broke up with her because 1.) she was cheating on him constantly and 2.) The way she treated his group mates was disgusting. She's back and is trying to win back Seonghwa but Seonghwa rejects her and says that he's found someone who makes him happy.

Nari is an anti of Hongjoong and is jealous that Seonghwa fell for him. She's also homophobic and bullies Wooyoung, Mingi and Yeosang foe dating the same sex and the three ends up becoming very depressed which angers San, Yunho, and Jongho. She makes Hongjoong's life a living nightmare by spreading lies about him, forcing Seonghwa to go out with her against his will and even asked her father to arrange a marriage between her and Seonghwa who refuses to do so because he supports the 98 line couple. This made Nari upset and blames everything on Hongjoong to where Hongjoong's mental health spirals out of control.

Will everything be back to normal in Ateez Land? Can Seonghwa fix everything before it's too late?
