This legit teaches me sh** ton. This is my guru. I shall be back for more context when I need it.

This may be ecchi,but the story is good, character development is good. The author even make every possible love route even the teacher😂 so you never fuss up like gotoubun in the anime. Which is something I don't understand why he get with yotsuba. For me I prefer asami and tsuruse ending, don't know why cause mabye their are my type. So if u wanna read some rom-com ecchi, this might be the best. 9/10
10/10 if without with teacher ending
