Levi: ?

Petra: *bites chocolate again*

Levi: *walks from behind her and taps her head a little hard*

Petra: Ah! *muffled* Heichō? You scared me!

Levi: What the heck are you eating?

Petra: *removes chocolate from her mouth* Chocolate, sir.

Levi: Is it good?

Petra: Would you like to taste yourself, sir?

Levi: *hesitantly accepts a piece* *bites it* *eyebrows raise in amusement*
