Tsukasa got up from the couch after hearing the doorbell, Rin stacking some blocks on a baby rug which she could crawl on.

He opened the door and greeted Rui with a smile. Len was being held in his arms, reaching his hands to try and touch the blond, who reached out his finger for the baby to grab.

"Thank you for coming again, Rui."

Tsukasa said, walking besides Rui. The latter approached Rin and greeted her sweetly, putting Len down on the rug with her.
