Park Sunghoon, Your ex boyfriend who had recently become the new CEO of the company you worked at... good for him... awkward for you

"Here are the papers you asked for Mr Park" you told him formally

"Why're you being so formal Y/N? We go way back" he says with a smirk

"I'd rather not discuss that right now and I would rather all of this be professional" you said

"As your boss I order you to call me Sunghoon, like you always did" he says again with a smirk
