And THAT is why FMC bother me in these mangas. "Fucking dense MC" my foot. Teasing is funny, but it's not an honest way of conveying feelings. Her friends mock him and she only ONCE apologized for that, and took her 39 chapters + extras. She hasn't defended him once.
Sure, she has done some "unnecessary" things, like the sick visit, but if you put it all in the scale, the winner isn't "she likes me". It's clearly "she's using me".
