is the redhead co worker really a bad guy?

Nope

OMYGOOOOD THANK U SO MUCH I LOVE HIM WITH ALL MY HEART

I prefer him actually. It's so sad because he could have been a great lover interest (like, their story and relationship is cute) but because a dog transformed into a human out of nowhere, he's destined to be the second lead.....

Exactly I’m so sad for him. ┗( T﹏T )┛

NOW IM IN PAIN PLS, I LOVE HIM SO MUCH

IKR !!! IT'S FUCKING SAD FOR HIM AND I HATE IT BECAUSE I LOVE HIM SO MUCH Their story could have been so good, even without this whole magical dog thing, it could have been so interesting...They could be such a great match, they have such a good potential to be the main couple.... But no, the author decided that a dog would be better The pain is real

I THINK THAT TOO ╥﹏╥
