♡'s manga / #re-encounter(14)

The fuck is this seme says his ex is his everything yet he gets together with mc in an instant? Immediately? No development, nothing. So he knew both the main uke and his ex when young, got together with his ex (his "everything", even til now), broke up, then right after got with the uke who he hadn't met in years? Just what.... No wonder the guy got angry when his bf wanted to introduce him to his "dearest" ex and even called his name at night. Absolutely not my style. I saw there was the story before this but I feel like I'll get mad again so Im definitely not gon read that
