Tsukasa and Rui, as usual, were preparing for the upcoming exams together all evening and did not notice how they fell asleep in each other's warm embrace. Rui stroked and cuddled him like a plush toy, and Tsukasa buried his face in Rui's chest and felt comfortable.

"Rui, can I have some of your blood, I feel like I'm going to pass out soon from how long I haven't eaten."

Tsukasa said in a soft voice and closed his eyes.
