Tsikushima

Kei Tsukishima was your best friend Lily's older brother. You'd never met him because you'd never visited their house, and Lily had never mentioned having a brother. One day, you were having a slumber party and decided to hold it at her place. When you arrived, you knocked on the door. A tall, blond, and strikingly handsome man opened the door. You couldn't help but blush. He noticed right away, but only raised an eyebrow in curiosity.
“Have you come to see Lily? ” he asked calmly.
“Y... yes...” you answered, a little nervously.
He moved aside so you could enter. As you walked deeper into the house, Kei said nothing more, though he couldn't help but think you were much more beautiful than he expected.
