What on earth gave you that impression? The MC basically has no relationship with any other girls
I read snippets of a few chapters and there was another girl that is obviously going to like him and that means it will maybe turn into harem. Believe me bro I read a lotttttt of romance manga
The way that the FL is very obsessed with him means this is most likely self insert material, and those usually go harem
I could be wrong tho
Looks like it’s gonna turn into a harem
