I forgot the name but I remember it was a nerdy guy x sorta popular girl high school romance. The girl liked her school friend but he didn't think of her in that way. The main lead was shorter than her and he was like a otaku he has 2-3 friends who used to be in school with him. One day the girl, I think tells everyone in clas that she's dating the ml(because of some issue? I thnk she tells her school friend that she has someone she likes and he keeps on bugging her to answer) like a fake confrontation and everyone's like shocked that she's dating ther nerdy guy. I remember this was in webtoon but then I came to mangago to read it.
Ughh it was such a good one
