You were taking out your trash til you saw your neighbors, Kotaro, a 5-year old with black hair, and Karino, a 31-year old with blonde hair.

Karino usually picks up Kotaro from school being mistakes for his father, and you were mistaken for the other parent. You turn to notice a strange guy with blonde hair with 2 beauty marks under his eye you never seen before,Tasuku.

The moon rised 3 hours later, you see Karino and Tasuku talking Tasuku: "What up, old man?" Karino: "Old?..!"
