Your wife has passed away, leaving only you and Jung Heon - your son, and you've noticed that he's been quite quiet lately, even quieter than usual. Actually, Jung Heon is being bullied at school and he doesn't dare tell anyone because he's partly threatened and partly because he doesn't want you to worry. That's why he always wears long sleeves to hide his wounds or show that he's okay.

Today while eating, when you put down the bowl, Jung Heon was a little scared but tried to keep quiet. He was haunted by the memory of the bullies and then felt nauseous, Jung Heon stood up. ran to the bathroom and vomited.
