My Girlfriend Wanted an Open Relationship, So I Broke Up with Her and Found a Sweet Yandere - Chapter 31

We were seated.

“Let’s start from the basics,” I said, lowering myself into the chair across from her. “What do you mean?”

I’m still flabbergasted. It probably shows. I’m trying to keep my face neutral, but I’m fairly certain I look like someone misheard something life-altering.

Hayami-sensei sat across from me in my cramped living room, auburn hair tied into a neat bun.

she wore lounge clothes—a cropped deep neck white tank top few sizes smaller than needed and grey sweatpants that bagged past her ankles, she looks…. different.

It’s distracting.

And she dressed so lightly while it’s so chilly outside, it’s like 2° there and she’s sweating too.

I keep my eyes respectfully unfocused somewhere near her shoulder.

“I mean what I said,” she replied evenly. “You can stay with me.”

The words land just as firmly the second time.

“At your place?” I ask, even though I know the answer.

“Yes.”

I let out a quiet breath. “Why would you even suggest that?”

“You need stability,” she said. “And I’m moving anyway.”

That makes me pause. “You’re moving?”

She nodded. “At the end of the month. I’ve already been looking at other places. Somewhere bigger.”

Huh?

“You’re not changing places because of me, right?” I ask quickly.

Her eyes widen a fraction, genuine surprise flickering across her face.

“Takahashi-kun,” she says, almost incredulous. “I don’t make housing decisions based on a student.”

Right.

I look away, feeling slightly stupid.

“I’ve been planning this for a while,” she continues. “The lease is ending, and I want somewhere with proper space. If I’m going to be studying again, I’ll need it.”

“Studying?”

She nods again, posture straightening just a little.

“I’m resigning at the end of the term.”

That knocks the air out of me more than the moving part.

“…You’re leaving?”

“Yes.” Her voice stays calm. “My current qualifications aren’t enough to move into a better university or a more permanent academic position. If I stay as I am, I won’t progress.”

That… makes sense.

“I need additional certifications,” she explains. “Possibly a postgraduate program. Research credentials. Right now, I’m underqualified for the roles I actually want.”

I stare at her.

In my head, she’s always just been… my teacher. Established. Steady. Fixed in place.

I forget she’s young.

Unbelievably young.

It’s almost more surprising that she’s teaching at all at this stage. Of course she’d want to aim higher.

“And while you study?” I asked stupidl, offcourse she has a plan!

“I’ll work with my grandparents,” she replies. “They run a family business. I’ve helped there before. It’s stable enough to support me while I complete my studies.”

Family.

Support.

A safety net.

I nod slowly. It all sounds structured. Thought-out. Practical.

“And that’s why you’re moving?” I ask.

“Yes. A larger place makes sense if I’ll be working part-time and studying from home. A separate room. Less cramped.”

She says it plainly.

Then she adds, just as plainly, “If you stayed there, it would simply be a practical arrangement.”

I let out a small, disbelieving breath.

“You say that like it’s nothing.”

“It doesn’t have to be dramatic.”

“You’re my teacher.”

“For a few more weeks.”

The reminder is quieter this time. Not defensive. Just factual.

I rub the back of my neck.

She’s not wrong. In a month, technically, that barrier disappears.

But it still feels—

“It’s not about rules,” I say. “It’s about… me.”

She watches me carefully.

“I don’t want to move into your place and turn into something you have to manage.”

“I wouldn’t be managing you.”

“It would still be like that.” My voice tightens. “Even if you don’t see it.”

She exhales softly. “Takahashi-kun, I’m not offering charity.”

“It still feels like it.”

Her brows knit slightly, the first crack in her composure.

“It wouldn’t be free,” she says quickly. “You’d contribute what you can. And when you’re stable, you can repay anything extra. We can treat it formally if you prefer. I’m not trying to—”

“I know,” I cut in.

She stops.

“I know you’re not,” I repeat, quieter.

And that’s the problem.

She’s serious. Thoughtful. She’s already planned her own next steps—resigning, studying, working with her grandparents. This isn’t impulsive.

And she’s calmly making space in that plan for me.

I think about my rent.

Ten days.

That’s how long I have before it’s due.

If I leave early, I’ll get the deposit back. That would help. It would give me a buffer.

But that’s my problem.

Not hers.

“I still have time,” I say. “I can figure something out.”

She looks at me like she’s measuring whether I believe that myself and after few seconds –

“You don’t have to prove anything,” she says.

“I’m not trying to prove anything.”

Am I?

“Then why refuse something reasonable?”

Because it’s…easy.

Because it’s not just reasonable.

Because she already did enough.

After the breakup with Haruka, she was the one who checked in. The one who made sure I didn’t completely fall apart. The one who stayed longer than she had to.

Leaning any further feels wrong.

“I’m not that desperate,” I say, maybe a little too sharply.

Her eyes widen slightly.

“I didn’t say you were.”

“I’m just saying,” I continue, steadier now, “if it doesn’t work out here, I’ll go back.”

“Back?” she echoes.

“To my family.”

There’s a brief silence.

Her eyebrow lifts, just slightly.

She doesn’t call it out.

Doesn’t ask questions.

Doesn’t say what we both might be thinking.

“Alright,” she says quietly.

In my head, I call my own bluff immediately.

Go back where?

There isn’t really a place to return to.

But it sounds solid. It sounds responsible. It sounds like I have options.

And I need her to believe I do.

“If it doesn’t work,” I add firmly, “I’ll handle it that way. That’s better than… whatever this would turn into.”

She goes very still at that.

A flicker of something crosses her face—surprise. Maybe even hurt.

“Whatever this would turn into?” she repeats softly.

“I didn’t mean it like that,” I say quickly. “I just— it complicates things.”

For a moment, she looks like she’s about to argue again. Her lips part slightly.

Then she closes them.

The shock settles in properly now. She hadn’t expected a flat refusal.

“You’re sure?” she asks.

“Yes.”

The word comes out clearer than I feel.

She searches my face, maybe looking for hesitation.

There is some.

But not enough.

“…Very well,” she says at last.

It’s calm, but not as steady as before.

I bow my head slightly.

“Thank you,” I say. “Really. For even thinking about it.”

She doesn’t respond immediately.

Then, softly—

“Takahashi-kun.”

Not sharp. Not scolding.

Just my name.

“You don’t have to carry everything alone.”

Silence follows.

Not peaceful. Just… unfinished.

She stands up.

“Wait,” I say.

She pauses.

I grab my spare jacket from the hook. “Take this too. It’s freezing outside.”

She hesitates, then accepts it. “Thank you… Takahashi-kun.”

Her fingers brush mine.

Warm.

No—hot.

Maybe I’m imagining it.

She slips it on and opens the door. Cold air spills into the apartment immediately.

She steps out.

Then—

“I’m sorry.”

I blink. “For what?”

“For putting you in that position,” she says quietly, back still turned. “I didn’t mean to make things harder for you.”

That catches me off guard.

“You didn’t,” I reply quickly. “I’m the one who made it awkward. You were just trying to help.”

She turns slightly.

And for the first time since I’ve known her—

She looks… worn.

Not composed. Not perfectly measured.

Just tired.

Guilt presses against my ribs.

“I’m sorry,” I say again, more honestly. “I didn’t mean to make it sound like you were overstepping.”

She gives a faint nod.

“It’s alright.”

It doesn’t sound entirely alright.

“Good night, Takahashi-kun.”

“Good night, Sensei.”

She walks down the hallway.

I close the door.

And immediately feel crappy.

Why did it have to sound like that?

She offers something carefully, reasonably—and I shut it down like she’d insulted me.

I exhale sharply.

At least walk her down.

It’s late.

I open the door again and step into the hallway.

“Sensei?” I call softly.

No answer.

I head toward the stairs—and that’s when I see her.

She’s near the entrance, one hand braced against the wall.

She sways slightly, like her balance is off.

“Sensei?”

I move faster.

Her head tilts when she hears me, eyes half-lidded. “Ah… Yuuta.”

Her voice sounds… off.

I step closer and reach for her arm.

Her skin is burning.

“What the— You’re freezing out here,” I mutter, but the second my hand touches her wrist properly, I realize—

“You’re running a fever,” I say, more to myself than to her.

She lets out a small, unfocused laugh. “It’s just… a little cold.”

[A/N: since I uploaded only one chapter, I’ll give you lead- remember this last scene as it’s not placed there for just a convenience of the plot, it has deeper meaning later into the story.]
