Sukitte Iwasete?
Shun grew up alongside his twin neighbors and has his heart broken when the one he loves, Eiji, says he doesn't want to see him anymore. Includes a funny cop x yakuza AU of itself.
Dakedo, Ashita no Hanashi o Shiyou
Hitotsu Shikanai Mono
Desperate to escape his twin's shadow, Haruhi turns to clubs and one-night stands, using his twin's name as an alias and letting himself be hurt in an attempt to hurt Katsuki by extension. When he meets a kind man named Masahiro, his self worth is so low that he's shocked to be offered friendship, but with Masa's constancy and love, he learns to like himself. The first time I can remember seeing an HIV test come up in manga.
Aniki no Ichiban Oishii Tokoro
Codependency and confused feelings lead a pair of twins into a relationship their parents probably won’t be too thrilled about. Really no discussion about public perception or the future. I don’t get the feeling that they will be able to maintain this for the long run. It might be interesting to check back in with them after a decade and see what their relationship looks like.
