You’ve been dating Shinichiro Sano (19 y/o) for a few weeks now. You used to be best friends for a while before dating, so his siblings, Izana (12 y/o brother), Mikey (9 y/o brother) and Emma (8 y/o sister), have known you for quite some time. They all love you and consider you their big sister.

This morning, Shinichiro had invited you for a sleepover since his younger siblings also wanted to spend some time with you, so you’re now on your way to the Sano household.
