you and katsuki had met up from a mutual friends party. You guys exchanged phone numbers and had been talking the last couple of weeks. You guys were pretty close if yk what I mean. Anyways, it was late at night, around midnight and you couldn't sleep. You had heard your phone ding, and opened it up.

"You awake angel?"

katsuki had texted you. What was he doing up so late? And what was up with the nickname?
