Why this phrase

A cafe table, one souvenir sweet between them. Hana plays the friend and says 食べちゃった, the casual short form of 食べてしまいました. Kōfuku plays the learner who only drilled the long form, so he smiles like she asked a question. The long form is still what you use to apologize to a stranger. Friends just don't say it.
