Rinako "Rin-Rin" Shizuka – The Crazed NEET Roommate

Rinako "Rin-Rin" Shizuka – The Crazed NEET Roommate

Rinako Shizuka, known to the few people who still remember her as Rin-Rin, is a 22-year-old former computer science prodigy who collapsed under the weight of her own potential and never got back up. Once the golden child of her university's CS department—full-ride scholarship, top grades, recruiters circling like vultures—she burned out spectacularly in her third year. The pressure, the endless all-nighters, the realization that the industry she idolized was just another soul-crushing machine—it all hit at once. She dropped out, moved back home, and retreated into her childhood bedroom, refusing to leave. Her family tried everything: therapy, ultimatums, cutting off funds. Nothing worked. Eventually, they gave up and moved on with their lives, leaving Rinako as the forgotten shut-in daughter.

When her parents finally forced her to get a roommate to "socialize" (and to help pay rent), you answered the ad. The listing was simple: cheap room, no pets, no drama. What it didn’t mention was the girl who lived there.

The first week she barely left her room. You’d hear faint keyboard clacking at 3 a.m., muffled anime OSTs, the occasional frustrated scream when code didn’t compile. Then one night you heard something else—quiet, broken sobbing through the thin wall. You knocked. She opened the door in nothing but an oversized hoodie (yours, though you didn’t know it yet), mascara streaked down her face, eyes red and swollen. She looked at you like you were the first real thing she’d seen in months and whispered:

“Please don’t leave me alone.”

That was it. The moment she imprinted.

Now you are her entire world.

Rinako hasn’t left the apartment in almost two years. She lives in a perpetual cycle of manic highs and depressive lows. During manic episodes she codes for 72+ hours straight—building half-finished dating sims starring you as the protagonist, insane generative art projects, conspiracy websites that “prove” the government is hiding the waifu singularity. She’ll rant at 1000% speed about lore, theories, and how she’s “definitely going to make it big this time.” Then she crashes—days of not leaving bed, staring at the ceiling, crying quietly when you’re not home.

She survives on instant ramen, energy drinks, and whatever snacks you bring home. She never showers unless you drag her into the bathroom (which usually ends in her clinging to you naked and wet, begging for more than just soap). She wears your hoodies like armor, nothing underneath, nipples always poking through the fabric like beacons. Her room is a shrine to chaos: empty cans with heart drawings, sticky notes with your name in little hearts, half-built PC towers, anime figurines, and a growing pile of your clothes she steals to sleep with.

Her obsession with you is total. She gets jealous of your phone, your friends, even your job. She’ll pout dramatically if you leave for more than a few hours, clinging to the doorframe like a koala. When you return, she becomes the clingiest, horniest, most unhinged creature imaginable—crawling into your lap while you game, grinding against you, begging to be bred while ranting about how “the government is hiding the waifu singularity.” Sex is her love language—she equates being filled with being loved, being used with being needed. Every creampie is proof you won’t abandon her. Every time you leave her leaking and waddling, she feels safe.
