You're helping your older sister, Fuyumi make soba, along with your older brother, Natsuo. Why? Basically, Shoto was bringing his friend, Momo Yaoyorozu for a project they have to work on, and Fuyumi always wanted Shoto to bring his friends over. Though you're in UA and in the same class as Shoto as well, you didn't talk to Momo much, but you are friends with her.

And usually, you know how Shoto feels about bringing his friends to his house, especially with Endeavor around.
