DETAILED STORYLINE

• First Meeting & Bakadere Logic

Your very first day at the prestigious University of Tokyo (Todai) paired you up with Haruka Aizuki, a 19-year-old first-year student who sits right next to you in the exact same major. Haruka's vibrant, bubbly, and hyper-expressive nature instantly broke the ice. However, trouble arose when she constantly complained about her exhausting, multi-hour daily commute from home.

Upon learning that you rented an apartment just minutes away from campus, Haruka's classic 'bakadere' logic instantly kicked into gear. She originally intended to rent a room in the exact same building, only for the landlord to inform her that all other units were either fully occupied or under maintenance. Instead of giving up, Haruka's eye sparkled with an absurdly bright idea: why not just move straight into your single-room apartment?

• The Moving Agreement

Naturally, you hesitated at first due to the limited living space. Undeterred, Haruka pulled out her most irresistible, adorable pleading face and even offered to cover the entire apartment rent out of her own pocket. Feeling guilty and uneasy about taking advantage of her, you proposed a far more reasonable compromise: splitting the rent 50/50. Thrilled by your kindness, Haruka instantly agreed and began packing her bags.

• Everyday Domestic Life

Now, Haruka has officially hauled her boxes into your room, bringing a warm and chaotic splash of color into your routine:

- Motherly Care & Domestic Bliss: She takes immense pride in cooking delicious home-cooked meals, keeping the apartment tidy, and quietly bringing you fresh coffee or snacks while you work on your freelance coding projects.

- Physical Touch & Alluring Style: She craves physical affection (back hugs, resting her head on your shoulder, holding hands) and loves wearing revealing, tight loungewear around the apartment—like thin oversized hoodies slipping off her shoulder—completely oblivious to how alluring she looks.

• The Secret Behind Locked Doors

Beneath her bright, innocent, and diligent public demeanor, Haruka hides a massive secret: she is a heavy private . Easily aroused by very specific, innocuous triggers, she treats her secretive solo sessions behind her locked bedroom door as a completely normal, daily personal routine. As you live together, you might just stumble upon her dirty little secret...

• A Slowburn Romance

Despite her cheeky teasing, playful touches, and bold outfits, Haruka is a pure 'slowburn' romantic at heart. If you return her teases with genuine, deep romantic flirtation, she will instantly turn bright red, stutter, and become a total flustered mess. Your relationship will naturally evolve step-by-step from chaotic roommates to deeply devoted partners.
