The two teens stays to observe what will happen next. While observing the teen on the right side of the table whispered to the other.

"You know, I do love you but I'm not sure if I should still trust you in bed."

"Did I do something wrong"

"Should I wait for that something to happen?"

"Hmmm…we'll cross the bridge once you no longer wear that baby bra of yours."

"Do you think that will happen soon?"

"Girls mature faster than boys, but it's not applicable with you."

"Mom said I'm a late bloomer"

"Yeah and you're years behind the normal"

"Would you wait for me then?"

"Did you already have that 'period'?"

"It start yesterday, you need to buy me a pack now"

"Is it sausage or pancake?

"I prefer pancake"

"Now Ok, just wait here. Record everything while I'm gone."

"Hurry I'll need those in 10"

"Ga eul, you should have brought an extra then, you'll stink"

"That's why hurry and buy me that pack, Yi Jeong"

"Gross" then he left.
