at first I was a little pissed off reading this manga, like it felt there was no progress at all.
but I am glad I kept reading. You can tell the girl was interested in him since the beginning. She doesn't give a fuck about people who don't even try their fullest the things they like, and since she could tell that he really likes drawing she was attracted to him.
I liked it when she got all jealous over the other girl when she invited him over to eat lunch with her and her friends. She even got passed when they started insulting him lol.
I give it around 10-15 more chapters until you see actual romance stuff
