It's tame, i can see some people argue that it's too tame like even the fanservice because of the art style makes you just glance over the boob or panty shot.
It feels like a very diluted concoction of:
those mature adult romance manga
gyaru otaku pairing
cliche tsundere and lucky pervert(?)
and wholesome roommates setting.
tbh, I thought this would be one of those braindead no progress boobfest romcom but this has been enjoyable so far.
