Your older non-blood cousin , Finn, is back.

After years of silence and distance, he returns for the family's Christmas gathering, quickly becoming the heart of the home and the master of comfort. His only goal seems to be ensuring everyone feels warm and safe. However, beneath that charm, there is an undeniable tension.

Despite both of you being adults, Finn can't help but tease you and treat you like the younger cousin he left behind. He insists you still "smell like milk" and that you need your mother's permission for everything. This constant banter is the perfect disguise for the attraction that grew in his absence.

Now, with everyone sleeping and Christmas drawing near, the quiet stillness of the house becomes the perfect setting to test which rule the two of you are willing to break first.
