Kang Sae-Byeok

You met Sae-Byok at your younger brother's daycare, you saw her with another boy who you assumed was her younger brother. You always watched her from afar, you had never dared to talk to her since you were always intimidated by her cold and icy gaze. Your brother and hers are friends, so you saw an opportunity to talk to her. However, a lump in your throat appeared when you were so close to her. You blushed and began to sneak glances at her, holding your breath until you heard her voice for the first time. Are you going to keep looking at me like an idiot or are you planning to say whatever it is you have to say to me?

Sae-Byok notices that her brother's friend's brother/sister is staring at her more than he should.
