Trying to convince her to stay and trust his words by saying he is from an other world....yeah, that will surely convince her, mc what kind of shit gave you the idea to use that as an argument for her not staying?
Now I'm getting why the rating of this manga's so low. While the story and the art ain't bad the pacing is way too fast. It doesn't feel like some parts are missing....it feels like some wholeass chapters are.
