So, my guess is Seo tried to befriend the guys with black hair on the other department.
And the other toxic masculinity dudes started gossips because, Seo was starting to get on their nerves, by saying that he was ''gay'' and the Dude ''beat'' him up thinking he approached him for more than just ''friends'' reasons... ? Bullying him to the point of him asking to be place in another department.
Cause all the talk we hearing right now about Seo ''implying'' things and flashbacks without context. So far A LOT of people got their opinions about him. Dude just want to do his job correctly.....
Also funny that Seo is seen as cold but:
Look like he could kill you but his actually a cinnamon roll
Meanwhile Baek:
Look like a Big cinnamon roll could actually kill you, burn your house down, sell your grandma, suplex your kids, curse your family for generations....
Me : Omg yes go help him ! Save him !
Him: I'm gonna fuck HIM !
Me: Yes ! ...Wait.... lmao
