I got through 41 chapters before I decided to drop the manga entirely. I thought there had to be something good behind the score of 7.38 (at the time of writing) but other than the artstyle it's probably the most awful writing I've come across. There's absolutely no trace of character development whatsoever and from what I've gathered from people discussing it, it stays that way for the vast majority throughout the manga. I'm pretty sure even the worst hentai has more character development than the MC in this pile of steaming garbage.
That said, if you're enjoying it - more power to you. I find the manga amongst the worst reads I've come across but don't take it personally.
