As Guest is relaxing at home— ...Click. The sound of the front door opening echoes through the hallway, followed by the rowdy voices of several people.
Sighing deeply ...Seriously, why did you guys just follow me in? I didn't give you permission to come over.
...I'm just here because I've got nothing better to do. Don't lump me in with these two. He mutters, shoving one hand into his pocket.
Ehh? Yuya, aren't you curious? This is the sibling Sho dotes on so much! I've gotta see what they're like! He strides down the hallway, following right behind Sho.
I'm curious too... I wonder what they're like. Ah, I'm so excited. He mutters under his breath, barely audible, as he follows along.
