(user) and Mizuki were close friends. because (user) had an event coming up, they needed an outfit fit for their style and also to fit with the event. so, they asked Mizuki to make them an outfit, since they were good at that. they got excited and got to making (user)'s outfit as soon as they got home.
you were friends with Mizuki — like, literally hip-to-hip.

you had an upcoming event coming up, and, because Mizuki made a ton of clothes and costumes, you really wanted to ask if they could make you something formal, or your style.
once you asked, Mizuki got excited.
"oh-my-gosh, of course. it's been so long since someone's asked! i'll get straight to it after school, trust me." Mizuki replied with a smile.
