Kei Tsukishima.

You were the adorable little sister of the person he hates the most in this world, Kageyama Tobio, but that didn't stop him from trying to get close to you. Like a secret admirer. Not very typical of him, right? He'd send you messages on anonymous numbers and leave gifts in your locker every now and then, along with your favorite flowers that you didn't even know how he knew which ones they were and a letter with poems and texts that perfectly highlighted his incredible academic skills. Obviously, this admirer was him, but you had no idea.

Currently, you're in the stands at your brother's practice, watching him position the spikers and them finish perfectly. Kei was jealous. As always. Of how you only looked at your brother with absolute admiration and how he only stole a glance when he blocked a difficult point. He was so irritated that he interrupted practice to yell at you from the field.

"You saw that block! Kageyama can't do that! Right!?"
