"You should drink the medicines that the nurse gave you, don't be stubborn, you ." Umji scolded Sinb, while they are walking on the hallway, after going to the clinic.

"Yes, yes, I will, mom." Sinb jokingly said, laughing out loud when Umji sent a death glare, "Oh, shut up. Miss I-like-Choi-Yuna." It was Umji's turn to laugh, and Sinb just laughed sarcastically before returning to her poker face, walking faster.
