Why Did His Wife Mention That?

At six in the evening, all of them began to leave in order to let Hiroki rest comfortably.

Shuichi and Taichi drove Kazuya and Himari to the bus stop just at the entrance of the villa community. The couple refused when the twins wanted to send them home.

"Bye-bye, see you next week!" Shuichi waved his hand at the couple.

"Kazuya, I'll text you later about the meeting," Taichi stared at his friend, "Ah, check your e-mail. I sent a few important documents to you."

"Alright," answered Kazuya curtly.

"Bye-bye, thanks for sending us here," Himari greeted them back.

The husband and wife waited at the bus stop. They were the only passengers there at this time. 

Ever since they moved into their new place, Kazuya rarely drove. The couple opted to use public transportations to go here and there unless it was necessary to use the car.
