Koinaka is a pleasant, short romcom, set in Tokyo and Sendai. The 3 main characters are in a love triangle, then they are seperated suddenly, after growing a little they reconnect. There's deception and coercive control on one side, immaturity and lack of committment from the other, no easy choices.
There's a lot of OnePiece references and the characters seem to be loosely modelled on characters from OP.
It was pretty odd the missing OP vol.51 was'nt replaced by Aoi, an avid comic collector, in the 7 years since it was published. ๐
