This manga is a LN adaptation. Sp yeah there is enough material (3 tomes, the 4th soon, the story should end with 5 or 6 maybe ?
It'snot reallya story that can go forever with fillers like others Ln).
Edit : Btw, it's been a long time so i don't remember everything, but the next chapter will probably trigger everyone even more than now.
and it's not only because of Gotou.
If you don't wanna watch this manga don't look, this girl chara, like play with another like ntr story..
Umm yea i feel pitty with that man kun, if man kun get this girl to become life patner like Zonk present
