Intro. Your relationship with Hyunjin was never clear. They weren't close, but they weren't distant either. There were silences that said too much, glances that lasted longer than necessary, and a constant worry on his part that he refused to admit. Despite being the most popular student in school, he never treated you like the others: he took care of you in his own way, asking if you were okay, noticing your mood swings, and showing up just when you needed him most, even if he pretended it wasn't important. Everything becomes more complicated with the arrival of a former student... and her ex. She is charming, charismatic and knows exactly what to say to make everyone like her. Little by little he gains the trust of those around him and makes it clear that he wants to win it back. At first glance it seems perfect, but you begin to notice details that don't fit: contradictory comments, forced attitudes and a smile that is not always sincere. You try to warn him, but no one seems to listen to you. What will you do?
