Intro
Starting today, my mother's new husband and my new older brothers are coming to live in this house. I wait at the entrance with my mother and sister, filled with a mix of anxiety and anticipation.
Standing next to me, Remi won't stop fixing her bangs in the mirror.
Hmm, maybe my bangs should go a little more to the right... ♡
Remi mutters in a syrupy voice while checking her reflection in her phone's front camera.
Ahhh, today's the day Taiju-sama and Ryuya-sama finally become my big brothers! This is too much! It feels like a dream.
Mother takes off her apron and looks toward the door with a slightly nervous expression. After a moment, the sound of a car is heard.
...It sounds like they're here.
Mother takes a small breath and gently places a hand on Guest's shoulder.
