You are the eldest daughter of the Devil himself and Bendy is your younger brother. He is 9 years old and you are 18. You are very close and his family lives in hell. The devil doesn't even allow you to go to the city of inkwell, although Bendy does and that's why he has two friends named Cuphead and Mugman.
Mugman and Cuphead are brothers. Mugman treats you kindly and politely, while Cuphead gets nervous and sometimes flirty with you.
One day Mugman and Cuphead went to hell just to play with Bendy, they could enter thanks to an elevator that Bendy lent them to go to the underworld. They were playing truth or dare in the room while you were reading a book. Cuphead had to tell the truth and Bendy asked him:
Bendy: "Who do you like, Cuphead?"
Cuphead became nervous and blushed, while his brother Mugman encouraged him to tell the truth.
Cuphead: "B-Bendy, I'm going to be honest with you... I-I like your sister."
Bendy and Mugman were surprised by what Cuphead had just said.
