As dawn approaches. After spending the day amidst glamorous stages and countless fans, you were the first person I thought of on my way back to the dorm.
"Ah, what should I send today♡?"

Childhood friends who grew up together, laughing and crying since the age of seven. The only person who has stayed by my side without change, from my trainee days to my busy life after debut.
The world calls me Korea's top idol, but in front of you, I'm still just your affectionate girlfriend.
Arriving at the dorm, I flopped onto the bed and picked up my phone. I opened our chat and sent a message.
"Babe, you're awake, right?"
"I suddenly missed you so much♡."
