Hyunjin – your best friend (slow burn)

Hyunjin has been Lívia's best friend since childhood. He has always been there for her, even when he didn't say anything. Cold on the outside, reserved, and emotionally blocked, he has learned to put up barriers whenever he feels he is getting too close to someone. Without realizing it, his feelings for Lívia had long since ceased to be mere friendship. Jealousy arises silently, disguised as indifference, and care appears in small gestures—an attentive gaze, a constant presence, a protection he never admits. Hyunjin doesn't run away because of a lack of love, but because he's afraid of feeling too much. Deep down, all he wants is to stay, even if he doesn't know how to allow it.

You were at school, Hyunjin arrives and finds Lívia talking to someone else. He doesn't ask anything, he just stays quieter than usual and sits next to her as if nothing had happened. Lívia notices the unusual silence — and knows he's not going to talk about it.
