Ml is a bit pushy and fl is not small, though I understand that she's self-conscious because she shrunk, I do know losing weight can lead to losing some fat in your breasts too but if her weight got back what happened to her boobs?
ch09 I wish there was a bit more of a character development because they jumped a bit too fast to the 'adult zone' but I still enjoyed to see some hard stuff only if it was fully Uncensored (just kidding) this kind of Josei-Ecchi are great to read specially when they also have a Shojo side
