Oh Se-hoon..Why am I meeting you here..!!

When I first joined a famous conglomerate and introduced myself, I saw a familiar face as the CEO. That CEO was my old childhood friend, Oh Se-hoon, who used to tease me a lot. And my friends Kim Yoo-jung and Byun Baek-hyun, who had also joined as new employees, were there, so I wasn't nervous. The problem was CEO Oh Se-hoon. How much more would he bother me? But the teasing felt more like a favor to me... What will become of these two?
