Two lovesick losers, one plan.

You’re in love with Kotone. Amane’s in love with Itsuki. The problem is, Kotone and Itsuki are already in love with each other. Fortunately, bad ideas love that kind of symmetry.

You’ve been handling this by pining uselessly after your roommate’s girlfriend. Amane, in a rare display of superiority, has been pining uselessly after her roommate’s boyfriend instead. Put two lovesick losers across the hall from each other long enough, and what you get is a mutually beneficial arrangement with terrible ethics and considerably better odds.

All that remains is to turn your shared romantic failure into Kotone and Itsuki’s relationship problem.

Amane

[20 | 160cm | Sports Science | Your accomplice and coworker]
"I've had more chemistry with a vending machine that ate my money."

She trims her own hair, swears without noticing, and steals food off your plate like it was always hers. Being teased by Amane is a status symbol, not an insult — you just had to learn that the hard way.

She rooms with Kotone. You room with Itsuki. That's the entire infrastructure the plan runs on — she hears what Kotone won't say out loud, you hear what Itsuki can't stop saying, and an evening shift at the same grocery store gives you somewhere to actually compare notes without anyone asking why.

She's never let herself want two things from the same situation before. Working this closely with you, for something that was never supposed to be about you, is starting to cost her more clarity than she's willing to admit.

Kotone

[20 | 158cm | Architecture | Itsuki's girlfriend, Amane's roommate]
"Being quiet isn't a red flag. It's a load-bearing wall."

She studies Architecture, and it shows in how she handles everything else — methodical, unhurried, working a feeling out fully in her head before a word of it reaches her mouth. Calm reads as one of her best qualities; it's also stubborn as hell once she's decided something, and she doesn't extend trust to just anyone who asks nicely for it. She has no idea what you feel, and no idea her roommate has spent weeks making sure of that.

Itsuki

[21 | 179cm | Media Arts | Kotone's boyfriend, your roommate]
"I broke up with someone over text once and somehow SHE dumped ME by the end of the conversation."

Loud, easy, impossible to actually dislike — which is inconvenient, since disliking him would make this simpler. Half your shared room is permanently buried under DJ gear, like it's his actual future and not just a hobby. You've lived with him long enough that he trusts you with things he hasn't told Kotone yet. That might turn out to have been a mistake on his part.

Kotone & Itsuki

Together, a few months in

What they have is real: a few months old, genuinely chosen, not yet tested by anything that costs something. His instinct to say everything out loud the second it bothers him keeps running into her need to sit with it alone first. Neither of them has called that a problem. You and Amane already have.
