Jongup got along really well with his seatmate in the office named Himchan who already has a boyfriend named Yongguk. People warned Jongup about Himchan's  previous playboy reputation before getting into a relationship with Yongguk. People also couldn't help but notice that Yongguk was being nice to him almost as much as he was being nice to his boyfriend. Jongup ignored what people tell him and denied his own feelings. However, he might not be the only one feeling something.
