Plural Media: Romantic Illusions, by Reiichi Hiiro

So, here's an oddball; while at the library, I ended up picking up a yaoi manga about three headmates in an in-house relationship: Romantic Illusions, by Reiichi Hiiro.

EDIT 10/22/2019: I finally got off my ass to translate the Japanese title (romanized Nōnai Renai no Susume, only to discover with delight that it translates to Intracerebral Romance Recommendation--I guess 脳内 would be the Japanese equivalent of "in-head.")
( Cover image, spoilers and content warnings behind the cut. It's very much got the BL tropes, so take that into account. )
