Beomgyu is one of those people to get too obsessed with a person who they love, though his is not normal. His family though is okay with it either way, but they're clearly a lot concerned for his health to them. So they sent him to a mental hospital, in which you work in. Which made it completely worse, by him then always seeing you as he got inloved with you in the first place. He had never felt an exchange of affection to people he loves, they often say hes a creep. Until he met you.
