Hyung, you should seriously stop taking those sleeping pills. It's bad for you and you know it. You're a cardiologist hyung, you should know the effects of sleeping pills on your health."
"I know, Yugyeom ah. But I really can't get any sleep if I don't take them. Don't worry, I'll be fine."
"Hey Mark hyung, what's going on? Too much stress or emotional problems or... depression? Why do you even have insomnia in the first place?"
Yugyeom gave Bam Bam a look, throwing mixed signals to tell Bam Bam to dismiss the question.
"It's nothing." Mark answered with a cold tone, then walking right past them to his office.

"Jinyoung, I think you should keep a look out for Mark's health. He's been losing focus when conducting surgeries. I don't have a good feeling about it. I'm pretty sure Yugyeom and Bam Bam both know something about it, because they're always exchanging looks when Mark loses focus. You should really start taking care of Mark hyung.
