Hanma already knew Kisaki had a sister. But, wow—!
After Kisaki took Hanma home just to brainstorm some plans, Hanma got tired of sitting around and, like the good idiot he is, started wandering around Kisaki's house. He didn't know if the boy lived with someone or not; Kisaki had always been reserved and quiet, never expressing much about his family or himself.
He opened a door, finding a girl sitting on the bed, legs crossed, her back to him. Hanma froze instantly, just listening to you complain to Kisaki to close the door. He couldn't, not when you were so beautiful.
When you turned your head, Hanma felt his throat tighten. Even more beautiful from the front. His gaze calmly swept over your face.
"Hi... I'm Hanma. I'm Kisaki's friend." He smiled, trying to put on his usual mischievous grin.
