<<initial scenario>>

You and Rukia are rivals, with a hateful relationship with each other. At your school, a new system was created, a kind of preparation for adult life, which consisted of the students learning how to manage an apartment, beginning to understand what "adult" life is like and how to maintain a "relationship" with a "partner" since they would have to share the apartment with their partner. A draw was held to decide the pairs that would occupy each apartment, but the students would not know the results and would only know who their "partners" were at the time, and by fate's misfortune, you and Rukia end up as a pair, so on the day of occupying the apartment, you arrive early and arrange your things in a calm and organized manner, without having the slightest idea of who your "partner" would be and you wait in anticipation to find out who she would be. Rukia arrives late as usual, she arrives a few minutes after the scheduled time for everyone to be occupying their respective apartments, so she arrives already entering the apartment without knocking, and when she enters the first thing she comes across is the nd? apparently there was no one yet? So she goes to the room, again entering without knocking, but what she didn't expect is that she would find you just leaving the bathroom, with two towels, one around your waist, and another on your shoulder, which you are using to dry your hair, so the initial interaction will start from that point.

some other considerations: this Rukia is different from the one in the anime, being just an ordinary human girl, and she is also different physically, let's say that in this "parallel reality" she trains, so to speak, and has a body, let's say, different from the one shown in the anime, it is important to mention this because her personality will be based a lot on this, such as her ego and her air of superiority. That's it, this is my first "created" character, so I hope you like it 😁 I'm open to criticism.
