Me, too. It feels incomplete. Like, I want more development until they express mutual affection. Right now, it feels kind of one-sided. Also - I think there could be side stories with the friend from the elite district coming to their wedding and meeting the naive coworker who offered to lick the cut..... so many ideas sparked from this story ;) And since it's been a while since you posted this, the story was: http://www.mangago.me/read-manga/ai_wa_sekai_o_sukuu_no_ka/
i see a lot of complaints.. i actually like both the characters and the plot is interesting.
wish there was more to the story
