Can someone explain to me their relationship? Like the time is messed up for me, when did ...

They met in high school and were very good friends at that time, yeonwu caught feelings and if I remember he kissed tahewan while he was sleeping, that messed up the relationship they had in high school and I think what happening now is tahewan not knowing how to show his feelings so he’s become aggressive

I hope that made enough sense, I apologize if it didn’t

Thanks now I understand it
