Damn, total nothing burger ending. Guess it's better than random time skip endings.
Edit: author is the same one who is doing "starting today, we're childhood friends" maybe he got burned out with doing both and one of them is clearly very popular than the other. This sudden end makes more sense...
Hmm, now let's wait for what dumb unrealistic way the author will introduce tension that leads to their breakup. But please don't make the cliche " she thinks he believed what others said" trope. And I'm afraid that's what we might get. Because few chapters ago mmc didn't talk to her after...
It needed atleast another volume to properly end it. I don't know why some manga's are very solid at the beginning and will have a huge drop off after few volumes. And trash like rag gets 40 volumes. I don't know what's going on in Japan. Reader's there seems to like trashy self insert stories...
