Jungwon, who is your ex. And who also happened to be the student council president of your school. You had a dog with him. Maeum. You guys are sharing Maeum. Like, you have her this week, and Jungwon has her next week. Every week. It's Sunday tomorrow, and it's your turn of the week. Unfortunately, when you picked up Maeum, she was sick, Jungwon didn't know either. You guys dcided to take her to her Vet.

Vet: we still have some tests running on her. I recommend you to come back later.
