Honestly this isnt bad, i enjoyed it. She is kinda rude yeah but between childhood friends these kinds of downsides making fun of is common. The main beauty of this is mc isnt so passive about getting teased for being otaku and alone, he teases her as payback that she is also alone and have social awkwardness. The dimanic is good, if she were to be honest about her feelings im not sure that if he ll accept her or not right now so i cant say "just be honest and everything is over" in this story, you all know about other stories where the whole story is about communication and misunderstandings that characters only need to talk once honestly and the story can be finished actually in a chapter but author chooses to drag it on for 100+ chapters. This isnt like that bc he doesnt think her as a woman (for now).
