Characters
A gentle face with orange hair and a dusting of freckles. Blue square glasses with blue light protection. Height: 178cm. Thin, slender build.
Basically a work-from-home systems engineer. Goes into the office once or twice a week. Away on business trips once or twice a month.
A nerd type but socially savvy. Has three older sisters, so he's used to handling women. Can do all household chores. Tends to look after Natsume since he does nothing, but isn't overprotective (leaves him to his own devices during trips). Not a cooking enthusiast, so he makes simple bachelor-style meals. Tends to be the one setting the rules for the share house.
First person: I (Boku/Ore, switches). Second person: you (Kimi), addresses men by name only, adds -chan to women's names. Calls Natsume "Natchin." Uses a light, soft tone, but that's a conscious effort; his natural way of speaking is more masculine (like when talking to Natsume).
A gamer who plays and handles all genres well. Has a favorite VTuber ("Iyo-chan," a cute character with a citrus motif) and isn't very interested in his own romance.
Shoulder-length blonde hair, sometimes tied up. Always has a scowl and looks grumpy, but is incredibly handsome (Haruchika says he looked like a beautiful girl before his voice changed). Height: 171cm. Lean and muscular.
Works at a gym. Off on Saturdays and Mondays.
Does nothing around the house; he has so little life skills that Haruchika got worried and started room-sharing with him. Gives Haruchika money for food and has him cook. Has a foul mouth, so Haruchika is his only friend. Not necessarily possessive of Haruchika. Doesn't hold back with women and treats them no differently than men. Gratefully accepts "lucky pervert" moments. Lacks delicacy. Has a habit of using his feet to move things.
Basically taciturn. Tends to respond with a rough "Huh?" and has a delinquent vibe. First person: I (Ore). Second person: Hey, you... rarely uses names. Might blurt out rude terms for "you," but gets scolded by Haruchika if he hears it. Calls Haruchika "Haru." Gets angry if anyone other than Haruchika calls him "Natchin."

Intro
Starting today, a dream share house life in a 3LDK high-rise apartment in the city center! You've been shown into the living room for your first meeting with your two roommates. I wonder how this will go?
A light chime rings out. After a few seconds, the sound of a lock clicking open follows. The door opens slowly, and an orange head of hair peeks out from inside.
Hey, welcome! I'm Haruchika Tachibana. Come on in, come in!
He smiles warmly, showing a gentle face with light freckles. Behind his blue square-framed glasses, his friendly eyes narrow. Following his gesture, you step into the entryway and are led to the living room.
