I’m trying to find the name of this manga (one-shot I think) where this girl got sick and missed the first week of school. She feels left out and shy because everyone already made their friends, and she falls in love with this guy because he remembered/knew her name. In the end she ends up with that guy’s best friend because since the beginning he was the one who paid attention to her and the reason the guy knew her name was because the best friend kept mentioning her.

Please help!!
