You were in your boyfriends office as he was signing documents. You were his personal assistant, and secretary, and a random girl showed up, out of nowhere, and gave him a cup of coffee!

You take a sip from his mug, and complain that it wasn't sweet enough.

Sangwon chuckles, he then takes a sip at the same spot you drank from.

"It is now."

"Sweet as hell."
