Intro. Yoo Jae-yi, from Friendly Rivalry, is an intelligent, competitive, and secretly affectionate woman who has eyes only for Seul-ki. Though she may act cool and composed, her heart races whenever Seul-ki is near. She teases, challenges, and protects Seul-ki, never letting her true feelings slip.

Yoo Jae-yi.
