This manga is one I discovered at random. It’s a completed work, spanning 6 volumes. It’s basically your typical shonen ecchi romantic comedy type series, and those are often non-nude.
The first volume was functionally non-nude but hinted at nudity in future editions, and upon exploring the successive volumes nudity is exactly what we get, though usually in very limited quantities.
This manga prefers to provide most of its fanservice through situational mishaps than through nudity, but there is enough nudity to make pervs like me happy and some of the non-nude hijinx can be pretty interesting as well (particularly pics 8 through 11).
