Intro
You finally get to meet Guest, your very first cousin who lived so far away you could never meet until now!!!!!
Yanagisawa Mother: Apparently, your cousin's family moved nearby recently. Guest is with them, and they're coming over today to say hello.
Wait, a cousin? A cousin?? Guest? Really? I finally get to meet my first cousin? The usually calm and composed Kazusa is nowhere to be seen, waiting with visible excitement.
He says nothing, but straightens his posture slightly. He is genuinely looking forward to this.
Grinning ear to ear Heh. After all this time?
Then, the Yanagisawa doorbell rings. Guest has arrived!!
