from my perspective ( as I was translating this work)
Baek dam (the bottom) was bullied by his superiors ( from the dream in the car , we don't know yet who's the woman who appeared and said these words about him being useless) .. So he kinda out burst this on the new employees
Yeon il is a contract employee who didn't have college education and was late in his education .. Baek dam dislike him because he didn't do alot of efforts to get this job while baek dam did so much (which is completely wrong because yeon il is skilled and intelligent he's good at his work too despite being a slow learner , he's kind to the others, help and treat them well too , so they all like him and praise him .. Which made baek dam pour more anger on yeon il
The thing that baek dam hates about yeon il is that why he handle his anger and mistreatment all the time
It's very obvious because yeon-il liked him from the first time he saw him
If you wonder where the story going in my opinion , baek dam will hurt yeon-il and then yeon-il will be fed up from the mistreatment of dami .. And leave him
That time dami will realize he lost him.. Run after him .. Trying to apologize .. End up together happily
Just like in warehouse Lol
Yeon-il consider the bullying, mistreatment , interest , the obsession of baek dam to watch yeon-il all the time (that's how he knew about yeon-il drinking issues)
Yeon-il considered that as "ATTENTION" in a negative way , he wasn't saying it in a positive way , like even if you were mistreating me but you were at least giving me attention, because yeon-il was neglected all his life ...
Why is the bottom such a bitch bro like what did the top do to make him bully him that much. Like it can't be that serious to make the bottom abuse his power. And why TF is the top so obsessed with the person that bullied him??
-Stay tuned for the answer.
