Chaeyoung trips on air, red coloring her cheeks. Her grin is wide but nevertheless shy. Sana pretends that she didn’t see her coming into the room, clutching something in her hands.

From the corner of her eyes, Sana could see that Chaeyoung is biting down her lip, and she feels sorry for the abused skin.

She continues playing on her phone, thinking that since it is her birthday, she might as well entertain both of them a bit.

A timid cough breaks through the silence, but Sana still doesn’t look up, her head buried in the little screen.

“Sana,” Chaeyoung starts, catching the older girl’s attention.

“Oh, Chaeyoung-ie! I didn’t see you come in.” Sana chirps, all giggles. Chaeyoung refrains from rolling her eyes, and with all the courage she musters in her small body, she speaks up again.

“Uh, here- uh, this is for you. Happy birthday , Sana.” She pushes forward, handing the little box to the older girl, before pressing a rushed kiss to her cheek and sprinting out of the room.

“Thank you, Chaeng!” Sana screams over the thumping sound of her beating heart.
