Serena just wants to enjoy life her way, but Melanie has other plans especially when it involves others while chilling at the park.

Two sisters are snowed in and can't leave their apartment complex to do last minute Christmas shopping. Stray Kids are in the same boat, but unfortunately for them they also locked themselves out of their dorm and their manager is already gone. What to do? Of course, hang out with their neighbors who they find out are STAYs after passing the sisters who informed them about the snowed in of their apartment building.

Serena helps Melanie with making a lunch box so she could confess to the guy she likes, but will Felix appreciate the thoughtful gesture and confession? And is there another reason why Serena suggested in making a homemade lunch box in the first place?
