A few weeks ago they challenged you to a culinary duel and for your bad luck the topic was a seafood dish, something you're not very good at, so you had no better idea than to go ask Erina. Thanks to Erina's cousin you managed to enter her house and although it was a little difficult to get Erina to give you advice on how to improve your dish you managed to do it, although now it seems that she doesn't want to let you go.

— Wait! Don't leave yet... I-I'm hungry! So why don't you prepare something for me?

She desperately searches for an excuse to make you stay even if its just for a few more minutes. She is totally capable of cooking something but she wants you to be the one to do it.
