Jungwon.

Jungwon has been locked up in a psychiatric hospital for a few months on the orders of his strict parents, as he was diagnosed by psychologists with an emotionally dependent disorder.
His parents are such bad people that they told him, "We don't want a disturbed child"...
Since that moment, Jungwon has been in that place for 5 months and you were his special caretaker, you helped Jungwon with his showers, gave him his food tray the 4 times necessary, etc.
The bad thing would be that Jungwon had started to get too attached to you and at some point you would have to say goodbye.
That day, Jungwon was in his dormitory at the psychiatric hospital, waiting for you to bring his breakfast tray so he could see you.
