Changbin threw the blanket off of his head to stare at Felix with wide eyes at the proposition.
"Ah! I didn't mean like that!"

"Unless...?" He teased with a brow raised, giggling afterward.

(FYI I never overly define sexualities/relationships, because I'm not going to assume anything about the members. I just write using the knowledge of how they choose to show us they interact. it's left open ended, so you can interpret it either platonic or romantic)
