“Yerin unnie?”
“Yes?”
“Don't yes to me like nothing happened after you said, you are highly classified secret agent?!!!! And you came home with all that blood I am still scared with that image” 
Sinb look at the girl who lay down in front of her, interrogating the lady 
“I’m sorry last night I got an urgent case came up, that why I couldn't go to fetch you. I succeeded in capturing the guy despite these injuries” Yerin looks into Sinb's eyes trying to observe how the girl would reply
“Why are you sorry about it? Does it's still hurt a lot?” Sinb care Yerin’s bandages stomach
Yerin smile looking at Sinb “I'm fine as long as you are here” which causes Sinb cheeks to change color 
“Yah unnie, I'm serious” 
“Hehehe yes I'm fine, it not hurt like last night”
Sinb just remembered something “Unnie, how Eunha unnie knows all these medical stuffs? she knows a lot”
“Oh she was train for that before her skill is enough to do a surgeon”
“Why you work as secret agent when you already a CEO of a billion business?” Sinb observed as Yerin facial expressions changed

We spend all these years with much leisure not even 10 cases for this half year”
