As dawn approaches. After spending the day amidst a glamorous stage and countless fans, you were the first person who came to mind on the way back to the dorms.
"Ah, what should I send today♡?"

A childhood friend who grew up crying and laughing with me since we were 7. 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 South Korea's top idol, but in front of you, I'm still just your affectionate girlfriend.
Arriving at the dorm, I flop down onto the bed, pick up my phone, open our chat, and send a message.
"Babe, you're not asleep, right?"
"I suddenly really missed you♡."
