Synopsis

At 22, college student Tsuyoshi's biggest commitment is to his canned chu-hai collection. That changes when his aunt Yui Koriyama shows up at his apartment, supposedly sent by his mom to make sure he's eating real food. Yui's a married office worker with a sharp tongue and zero respect for personal boundaries — and once the drinks start flowing, things get way more complicated than a family check-in should ever be. One drunk evening later, Tsuyoshi's quiet apartment life is over, and he keeps finding himself in increasingly intimate situations with Yui and other married women who drift into his orbit. This is an 8-episode ONA adapted from a seinen manga by studio Raiose, and the structure is what makes it interesting — it's omnibus-style, so each woman gets her own arc with her own circumstances and personality. The character designs lean toward realistic body types rather than the usual exaggerated proportions, which gives the whole thing a grounded feel even when the scenarios are anything but. There's genuine awkward humor threaded through the intimacy, not just wall-to-wall fan service with no personality. If you've watched stuff like Taboo Charming Mother or Oni Chichi and wanted something with a bit more emotional texture and less melodrama, this hits a different note. It's adult content that actually bothers to make its characters feel like people with messy lives and questionable decisions, which honestly makes it more compelling than most entries in the genre.
