"Ah, Bret. Why are you here?" Minkyung tried to squat down 

"Eunwoo umma sent me here." Bret was jumping up and down.

"Bret-ah, sit down here. okay?" Minkyung smiled warmly. Bret nodded his head and sat down.

"Minkyung, it's nice to see you."

"Nunu!" Minkyung walked and hugged Eunwoo.

"How' are u?" Eunwoo asked.

'I'm okay. By the way, why are you here?" Minkyung asked as she was reading through her document.

"Ah, bret wanted to see you so I thought I can do him a favor. Besides, he is disturbing Chanie's nap."

"I'm sorry. He is as hyper as my partner."

Minkyung just smiled.

"By the way, Siyeon asked, do you want to come over for dinner."

"Sure. Why not?"

'Okay, I will see you later." Eunwoo walked out from the office. Minkyung was concentrating reading her documents so she didn't notice there's someone had walked into the room

"You shouldn't tire yourself." Minkyung looked out from the voice and was shocked when she saw the one that standing in front of her.
