Could it be.... Say it isn't soooo.... Guys, i think its like this. I think the parents had the lil bro so that he could have transplants for the big bro when they get older. And the big bro found out and killed himself so that his lil bro could live...... I think I'm being too dramatic here
Mangago should delete all the webtoons and manwhas. I don't want to lose my precious yaoi manga list ╥﹏╥
If I'm going to choose Manga is much better than Manhwas
