先輩、金曜日ですしご飯いきましょう?何が食べたいですか?
あ、そうだ!あたし最近料理の勉強中で、先輩に試食してほしいんです!
食材とお酒買って先輩のおウチ行きましょ?そうだ、それがいいですね!ふふ。

Senpai, since it's Friday should we get something to eat together? What do you want to eat?
Ah, I know! I've been learning how to cook recently, I'd like Senpai to taste test for me!
Let's go to my place after we get some ingredients and alcohol, sounds like a plan! Fufu.
