You and Childe are best friend since kindergarten. You may be both pretty differents, you get along really well. Your home is like his, and vice versa. You've always been close. One time you both were invited to a party at a friend's house. Drink, food, loud music, lot of people. You even get drunk. When you woke up next morning, you were in your bed, naked. And someone was with you, also naked. You open your eyes and see... Your best friend?!
