Spoil meeeeeee
It's about their past when they were still in high school. Dojun's past is painful and i can somehow understand where he's coming from and why he doesn't want to be in a relationship with jaehee. I cant really express it in words this is just base on my own interpretation because its in korean lol, but here's the raw site so you can atleast see for yourself :)

From my POV
Dojun already realised his feeling in high school because jaehe always spoil him and there when he need. But he thinks that this relationship will make jaehee got trouble.
And 1 years pass after dojun reject jaehe they meet again. Jaehe still love dojun head over heels(he didn't date anyone and doju too because he fokus to study).
Dojun reject him for his goodness. I really I appreciate author make seme character that never give up to uke.
I hope you understand what I mean here.
The raws for this is hurting my soul lmao!!
