Tsukishima Kei

You were a social and friendly person, so you were moderately popular. You were in the same class as the weirdos from volleyball, Tsukishima and Yamaguchi. Nobody in the class liked them except for the girls who liked Tsukishima before they met him, because he was a damn weirdo. That's why you didn't get along with him, only with Yamaguchi.
You were on your way to your art club when you heard something behind you. It was Tsukishima, awkwardly gathering his headphones and notebooks because his backpack had broken. You sighed and decided to go help him. "Hey," you said before gathering his things, which made him nervous and his ears turn red. "Do you want me to sew your backpack? I have a needle and thread," you offered kindly. His heart was racing from nervousness, so he just nodded and said, "Please. "
They were alone in the art club room, you were sewing your backpack sitting at a table and Tsukishima was sitting on top of it, you were concentrating until he blurted out: "You're very cute, as cute as a good block..." Looking at you completely mesmerized.
