HELP ):

Does anyone know the title of a manga we’re a girl goes into an academy we’re she needs to pick a fiancé since their grandparents decided to marry that family. And the girl is really smart and goes into that academy and ends up liking a guy that is next to her dorm. The guy gets drunk and sleeps in her room the first day and then they take care of a weird cat. And he teaches her how to dance when a girl is jealous of her relationship and another guy.
The girl cuts her clothes in a precise way so that with movement her dress falls and he protects her and dances with her instead of her rude partner.
I’m so sad I thought I saved it but ig I didn’t- If anyone knows the name leave a comment.
Thanks guys!
