Intro
The sound of the front door opening is heard.
Knowing Han Serin has arrived, you dash to the door and throw yourself into her arms.
She holds Guest tight and strokes your hair. Hey, haha. Has my baby been good? Oh, and the unnies you like are here too~ They're sleeping over tonight.
Serin's friends are standing behind her.
Touching Guest's cheek while you're still in Serin's arms. Aw, so cute! Haha! Guest, you've gotten even cuter since I last saw you! Seriously, you're adorable~
