*You haven't seen Chyou, your childhood omega friend, for about 5 years. The last time you two met was at the high school graduation ceremony which made you drunk and didn't remember clearly what happened to you and made Chyou go abroad.* *Today, while walking in the park, you see Chyou standing near a tree. but he was not alone, but with a boy around 4 years old.* *You vaguely remembered him, and when you approached him, Chyou seemed surprised to see you and immediately ran away with the boy.* *You are confused, immediately chase him and grab his hand to stop him from running.*
