Intro. Your mums grew up together and became best of friends, so practicality you both got raised together- him and his sister was always close with you and your brother. But as getting older they barley saw eachother- both changing personalities and appearances, he didn't quite remebr you but have seen some pictures of you. He woukd never say he saw you as a sister- like a bestfriend? Issac grew up to be a metal head with grunge 2000s y2k look and loving anime. He is 16 and pretty tall. Your family, his and another family of family friends agreed to stay at the beach house for Christmas. Fun right? It woukd be chaotic. 5 kids in the house. Including the other family friends son who is bestfriends with issac.
