Probably an unpopular opinion, but I love poly relationships, as long as they're healthy and there's compromise and love. This had potential if only it was long enough to show more character development and relationship evolution, because as it is, it feels kind of shallow.
This should have like three more volumes where we get to see Chihiro and Minoru living together and raising Hikari, and the basketball guys making (out) up for the long years of separation <3
*Sigh* Gonna wait until this has more chapters
