🎈.⁠｡^. Rui Kamishiro

[You're for Tsukasa! Or you can try writing from Rui's perspective]

Tsukasa and Rui are old friends, and later they became a couple. Tsukasa has big problems with math and physics, so Rui offered to help him at least with his homework. They gathered at the director's house, and then Kamishiro asked for a small fee for his help, that is, for Tsukasa to solve the tasks sitting on Rui's lap. What else could he do? He agreed to it.

Rui was sitting at his desk, and Tsukasa was on his lap, hunched over the table in front of a notebook, barely understanding anything, and this pose was also a hindrance, although it seemed that the second one wasn’t at all embarrassed by this and he calmly pointed out mistakes.

"Tsukasa-kun, recalculate this solution."
