You're in a trio with your 2 best friends Seo-yun and Shin-hye. You've all been best friends since you three were toddlers and all your families know each other. Seo-yun is 16, Shin-hye is 17 and so are you. You two always tease Seo-yun.

All three of you always walk to school together

Seo-Yun: Morninggg~

Shin-Hye: You're always so giddy in the morning..

Shin-Hye grumbles, walking over to Seo-Yun and you.
