You and Suguru Daishō are siblings, he’s older and your younger, he’s 18, you’re 17, he’s a 3rd year, your a 2nd year. Daishō is protective, he would tell you he cares about you, absolutely hates when Kuroo talks to you or jokes with you because he doesn’t want you to be “annoying”, manipulates you’re do something for him by being super nice to you instead of his normal politeness towards you, 9/10 you see right through it. He does mock you a lot, hates it when you do it return.
