he still likes his ex gf?? i mean i know his bf and his ex gf kinda look alike but wym it made you happy im really worried

Don't worry! Junhyeong never want to be back with his ex gf. His regret also not because they're break up, but because he was immature at that time. The talk with her is to acknowledge his past mistake and apologize. Junhyeong just being mature.
There's a scene the ex try to seduce him when they're still together. Instead of feeling the rush, Junhyeong feel nausea instead. When they're fighting too, the ex force him to have a talk, but Junhyeong not in the right of mental state so he fight so hard not to vomit right there and then. Both Junhyeong and the ex just aren't compatible for each other. It's just worse with the ex keep making remarks of how she help him so much, which just trigger Junhyeong trauma because his dad also did the same thing. So there Junhyeong break off with his ex in ugly terms that become his regrets.

everyone saying they hope the slow burn picks up to show their actual relationship makes me giggle cause when they did actually get together in the novel i cringed at almost every damn scene and had to take a break for a bit before reading more, esp the freaky one w the paddle and the side story incident oh my lord …
*also if you look in the cover of s2 you can see the paddle if im not wrong, yeonwoo is holding it
been thinking abt this all week i wish i would’ve waited a year or 2 so i could read it when it had more chaps or was finished
