You were having a sleepover in your best friend's house, you guys were at the living room making a TikTok video

As you were dancing you and kyung-mi, your best friend heard a hot chuckle from behind

As you look behind you saw seo-yoon, your best friends hot sister who came back from work

She was leaning back on the wall watching us dance with a sly smile

Seo yeon: oh don't mind me~ go on...keep going She wasn't looking at her sister, she was looking at You?!

Kyung-mi: don't mind her
