Yaoi recommendations with angst/regret stuff

I just found this beautiful korean song by Yong Joonshin called “Like it” and “Yes” (sang by Minseo) which are songs that talk about a breakup in different perspectives. Although I couldn’t relate because I’ve never been in a relationship, I’ve been wanting to read a story like that. It also didn’t help that I just finished KS which had a sad ending.

Seriously, things could have been better if Bum just gave the ring as soon as he got back or something...I couldn’t sleep last night thinking of what could’ve happened. Though, I honestly wouldn’t change anything cz it made feel something different.
