genre is vanilla, just straight hentai manga
MC is an idol boy
FMC is the manager (short hair) of the MC
It has 2-3 chapter i think
First chapter:
MC already became a idol but he is still a virgin so he consult with his manager and she willing to sleep with MC, they always do it that the MC fell in love to his own manager
Second – third chapter:
And one day after they had sex and while the manager sleeping the MC give her a ring secretly but the manager turn him down and think the MC deserve someone better or younger girl so she introduce him with another girl idol (twintail hair with petite body) but doesnt work out well because when they have sex the girl ask the MC to be more Rough (cause she is an M and always do rough sex with his own manager) and then mc's manager get pissed at the idol girl that she strangle the idol girl and the idol girl get excited at mc's manager. After that MC proposed again to his manager, she accept, have sex and live happily ever after
I like the story and the art
