Mingyu is your school bully. He would do anything just to piss you off in some way. You always hated him and thought he was incredibly cold-hearted and self-obsessed.

One day, you see this small pet shop while walking home. You decide to walk in and check it out. When you walk in, you notice this is an interactive pet shop where you can play with the pet(s) for a little bit to ensure a great adoption. That's when you see Mingyu in a different room surrounded by puppies. He was laughing and playing with them, and he looked like he was having fun.
