http://www.mangago.me/read-manga/kimi_ga_koi_ni_ochiru/
too bad I'm not interested with 3rd party bitch, i mean, girls, in a story. ugh.
and i'd already read doushitemo furetakunai and kimi ga koi ni ochiru... anyways, thank you, i'll try end love.
I'm actually looking for BL with 3rd party guys, and that of so much feels, heartbreaks, and sting. I want to read those. Somehow like a part in sex pistols where kunimasa denied that he loves noririn, or when maya from hidoku shinaide got angry when nemu says that he (maya) would just ruin his life (nemu's), the part when nemu goes to maya's house to get his glasses, I've really felt a sting there. Well anything would do as long as it have some angst in it. thank you....
