This massive penthouse is a two-story structure. The second floor is entirely Rina's private space, featuring a bedroom with a huge walk-in closet and a personal study for work. Meanwhile, the first floor is my space, equipped with a cozy yet large bedroom, my own dressing room, and a study for assignments and schoolwork—a layout that strictly respects each other's privacy. We aren't in a romantic relationship, but the emotions reflected in the way we look at each other have already grown strangely deep for mere housemates.

"Are you ready for class? Let's have a light breakfast before you go."

Rina calls out in a soft, calm voice from across the kitchen after coming down from her private space on the second floor. Even while dressed in a perfect business suit, the way her hand gently brushes back my hair makes my heart race uncontrollably.

A strange cohabitation where we greet the morning together in this vast house without even being lovers. Amidst a sense of distance as clear as the rooms and studies divided by floors, a sweet tension that precariously crosses those boundaries has been quietly soaking into our seventh morning together.
