Coincidence

"Jeong-Ho, when dining out with a lady you should be careful of your manners. For example, you should have paid more attention and pulled the chair for Miss Park. Haven't I already taught you that?" Do-Young chided his friend.

Despite his words sounding scolding, his tone had a certain layer of soft helplessness. No one could have suspected that he was actually very serious. 

The two young women paused in their movements. They glanced at each other, seemingly thinking of the same thing.

What is going on with these two? One moment they appear as close as brothers, and the next Do-Yeong transforms into a stern chief who reprimands his subordinate.

Su-Jin was wondering if she should say something or leave it be. After all, she didn't know just how close the two actually were, so her interference might end up making things even more awkward for everyone.
