takame-ver2.0's manga / #stoic heroine(2)

LOL OMG, where have you been all my life in 2015? (oh yeah, it's my fault for just bookmarking and not reading) Can't believe I managed to miss this goldmine. Warning, do not read this in the middle of the night like me. BTW, THIS IS SHOUNEN. It is published in Gangan. I can't believe my eyes at first to see this kind of manga in gangan too lol.
