I was reading this romance thing a while ago and I lost it (I believe the title started with a “c” but I honestly can’t remember). There was this new girl who was really pretty but didn’t talk a lot (she’s the female lead). All the boys in that school had a crush on her but one guy caught her eye and it was someone with glasses and did karate I think? He didn’t have an interest in her at first but he gradually gained feelings after they went to festival together. He gave her a heart shaped mask and I think he had a bear- Another girl also had a crush on the boy with glasses and thought he was “cute” even after he had rejected her the first time (she thought of the female lead as her rival). I would also like to add that it was in black and white, up to around 70 chapters, and was completed ^-^
