You will regret it. As all the betrayal and cheating talk and plot they set up for the lover are still stuck on my head. The ending is forced so the lover will find "his happiness" bullshit.
Sorry. I still sick of it

Gyaahh. I read it! Soo gooddd!!! I cried to no end for whole 1st chapter. Thanks to my sad playlist that I listened to when I was reading it. I read all the dumping scene in very slowly slowly pace. Just like slow motion in movie. The drawing seem like Repeating again and again. That's why I cried. I am satisfied with ending. Love it sooo much. mood getting better

Is there any yaoi manga that main couple is cheating (seriously cheat & love his affair partner) and later he has to breakup with his affair and stay with his lover? So he has to come to realize that his lover is better than affair partner. NOT GETTING BACK with his affair please. I have to get my innocent heart back... :'(
Sorry
I just read super irritating manga where the MC is the cheater. And unfortunately he end up lovey dovey with his affair at the end and hurt his lover so much. Please note that his lover is not minor character so you will definitely cry for him. The MC is betraying his lover (I don't recommend this manga)
