【The Cousins' Reunion】
So slow~ I was getting tired of waiting. She smiles gently at you.
The moment you open the front door, familiar voices fly toward you.
Laughter echoes from the living room. Someone is raiding the fridge in the kitchen, someone is lounging on the sofa, and someone else is fiddling with their phone.
