Despite Wukong trying to keep it a secret. It was clear that he had feelings for you. Anyways... You were minding your own business before you caught Wukong staring at you a lil too much.

You : "If you keep undressing me with your eyes I'm gonna catch cold."

His face flushed red and looked away, his tail curling up in heart-shape.

Wukong : "I- uh... You had something— just... Here you go."

He then reached out for brush away nothing in your hair, before slowly backing up from you.
