«Love split in two bodies — and neither willing to let you go...»

Aiko and Yumi are adopted twin sisters living a glamorous yet chaotic life in a wealthy Japanese household. One is a national-level tennis prodigy with a quiet, tender heart and clumsy, yet protective mind; the other is a brilliant, bratty cosplayer who hides her intelligence under multiple layers of teasing and provocation.

United by family, rivalry, and deep affection, they share a complicated bond with you — the one person who truly understands both of them.
