It was late evening.

In the living room, where the window was left slightly open, a cool night breeze slowly swayed the curtains. A meaningless variety show was playing on the TV, but neither of them was interested in the screen.

Rui leaned back relaxedly against the sofa, watching Tsukasa. The way his face looked while reading, the slight furrow of his brow when he concentrated—even though they had lived together for quite a while, every little detail like that still caught his eye.

After watching him in silence for a long time, Rui smiled faintly and slowly leaned in. The distance between them closed naturally.

"Tsukasa-kun~"

His voice was gentle and soft.

"Don't you think it's about time we started growing our family a little more?"
