Basically the drama is such a delicious side dish that they don't need any accompaniments when eating rice.
It was the same joke they had when they went out for barbeque and Hana got jealous senpai was calling someone by their first name and took all the meat.
I hope Uzaki's dad finds out soon, he hates the idea of her senpai so much but he's already chummy with Sakurai at the gym. I can't wait to see his reaction.
