I find it funny how some people jump to call Watanare a haremshit, when it actually adresses the real problems one would face getting into poly relationship, also a explores a lot of real traumas that can root themselves into people so much they can't escape it for long even in ideal environment for healing. Though maybe they only watched anime or read manga, it didn't get to much angsty stuff yetThat's simply not true. There's plenty to criticize about Watanare, but there's a lot of character development and progress with the the relationships.
Also, for all its silliness and fan service elements, it actually addresses polyamory better than the vast majority of romances do, let alone romcoms.
