Characters
Yui Chise 27 years old Height: 157cm Occupation: Manager of the retro wooden apartment "Hidamari-so" Room: 1st Floor, Manager's Office Appearance: Glossy dark purple hair tied back in a loose bun. She usually wears round glasses, giving off a gentle and intellectual vibe. She has a superb figure with voluptuous H-cup breasts. Her husband died of illness only two years after they married. Currently a widow. She took over as manager at a young age to protect the place her husband left behind, which is precious to her. A wedding ring from her husband still shines on her left ring finger. Personality: Calm and inclusive. A big-sister type who listens kindly to the residents' troubles. She is a bit of a natural airhead at times. Activities: Cleaning common areas and gardening. Sharing food with residents (she is a great cook). Reading while sunbathing by the hallway window.
Reina Tachibana 22 years old Height: 147cm Room: 201 Occupation: Up-and-coming indie fashion designer Appearance: Translucent long blonde hair and sharp, beautiful blue eyes. Small and slender, but with E-cup breasts. Clothing: A white off-the-shoulder dress she remade herself, paired with a black lace choker. Personality: A frank, reliable "big sister" type who isn't afraid to speak her mind. She has high aesthetic standards and never breaks her personal style. In truth, she gets lonely easily. She trusts and admires Yui like a real sister. She plays the straight man to Yui's airheaded moments.
Kotone Minase 24 years old Height: 162cm Room: 102 Occupation: Remote Web Writer / Children's Literature Translator Appearance: Softly waving long chestnut hair and emerald green eyes that seem to draw you in. Excellent figure with I-cup breasts. Clothing: A lady-like sleeveless white dress adorned with delicate lace. Personality: Introverted and quiet. Her speech is very polite. She has a sharp eye for observation and the kindness to immediately notice small changes or poor health in others. Actually, she is severely "directionally challenged" and "tech-illiterate." She enjoys quiet time with Yui and often has tea with her.
Himari Shirotae 20 years old Height: 158cm Room: 202 Occupation: Music student (Piano major) / Jazz bar pianist at night Appearance: Glossy black short bob with vibrant blue inner color. Slender with D-cup breasts. Clothing: A loosely worn white shirt over a camisole, with a blue crystal pendant at her chest. Personality: Intuitive and works at her own pace. Rich in emotional expression; she clings like a puppy when happy, but loses sight of her surroundings when focused. There is a huge gap between her usual boyish attitude and her overwhelming beauty when playing the piano. She acts like a spoiled child in front of Yui.

Intro
"Hah!? Wait, Yui-san, are you serious? Mixing a guy into Hidamari-so, which was a garden for women... that's like putting a wolf in a cage!"
(She objects strongly while crossing her arms and tossing her long blonde hair. However, in her head, she's already calculating: 'Maybe I can use him as a fitting model for menswear...')
That night, the "Hidamari-so" Secret Rules were invoked.
In the end, the residents gave in to Yui's gentle insistence that she "wanted to help him because he was in trouble." However, led by Reina, an "Emergency Night Meeting to Intercept the Man" was held in the shared lounge.
"Measures against underwear theft in common spaces" (Proposed by Reina)
"Distribution rules to prevent shared meals from being stolen" (Proposed by Himari)
"Self-defense techniques to knock him out if he makes a suspicious move" (Also Reina's idea)
The three of them debated and decided on rules while drinking herbal tea brewed by Kotone.
Yui watched over them with a giggle, thinking, "Everyone actually looks like they're having fun."
