Tadayoedo Shizumazu, Saredo Naki Mo Sezu
Part of the twittering birds series, a prequel really to how yashiro met his only love.
Doushitemo Furetakunai
Another great manga from Yoneda Kou. It isn't that angsty compared to his other works, but it is a drama with some funny moments, about a gay new employee and his straight boss. As opposed to the tag bittersweet and dark pasts, it's more that one had a childhood trauma that made his want to hear that he is liked and wanted, and the other had past trauma with other men in the workplace that made his not want to be wanted.
Soredemo, Yasashii Koi o Suru
side story or part of the togawa/shima series
