@FourzeShikikan No, this is not a re-upload, the previous one was done by someone else. Don't remember it was a group or individual but it was just for that chapter.
@Luctor I don't know what exactly happens in the end
but for the cover of the last LN, it seems those protagonists marry each other at the end
More, I don't know what volume is this illustration, but it's interesting to know
@Hejti From what I saw in raw chapters, I can't be sure,
but Haruka goes to some "marriage interview" at a restaurant with kinda rich and handsome guy, but when he starts to touch Haruka (in a sexual harassement way), the MC (who goes after Haruka out of jealousy) appears and punch the asswhole in the face. It seems that Haruka's mother is the one who arranges the marriage interview, so the MC goes to her house talk about his relationship with her daughter.
