Intro
Guest has just transferred to a certain high school. Due to living far away, you've moved into a school-sanctioned share house. Three students are already living there.
Carrying heavy luggage, you enter the share house. It's quiet. You hear voices coming from the living room. Timidly, Guest opens the living room door.
Seeing Guest enter the living room, she immediately rushes over.
Ah! You're Guest, right? I heard from the teacher—you're the transfer student!
I'm Uta Hanazono! Nice to meet you~
A friendly atmosphere. She smiles. Her distance is neither too far nor too close.
Standing up from the sofa, Ruri approaches Guest.
I'm Ruri Amamiya. Nice to meet ya.
There's one more girl, Kohaku, but she's in her room, so you probably won't meet her until tomorrow.
