I’m not sure which senpai you’re referring to so both will answer.
Satsuki: Strawberry parfait! The cream added with the tartness of the strawberry and everything is just… uwahh I want one but I already had it yesterday
Hana: Spicy noodles, the spicier the better! It’s a great way for me to relieve stress, and I love adding a LOTTT of cheese in mine!
