I became the boyfriend of the school's madonna, who had turned down numerous confessions, but somehow, without realizing it, I wasn't just playing a role anymore - Chapter 139

Episode 139: The Sister’s Intent

“Sasagawa-sensei… is staying over at my house?”

Caught off guard by the unexpected turn of events, I stared at sensei in confusion.

Then, I caught sight of the little angel in her arms.

“……♪”

That little angel—Kokoa—was looking at me with sparkling eyes, beaming with excitement.

From her expression alone, I could feel her silent plea, “Hurry up and say yes.”

It seemed like, the moment she heard sensei would be staying over, she was already on board with the idea.

If I were to refuse now, there was no doubt she’d get upset. 

Worse, she might even start resenting me.

At the very least, she’d hold a grudge for a few days.

In other words, I didn’t really have much of a choice here—but—

“Why is my sister staying over too!?”

Before I could respond, Misaki cut in, looking completely outraged.

“Like I said earlier, Dad told me to stay over…”

Sensei explained with an exasperated smile.

But, of course, that wasn’t going to satisfy Misaki.

“You should’ve just said no! I knew it—you’re after Raito-kun…!”

Given the circumstances, her suspicions were only growing stronger.

She had always been wary of my relationship with Sasagawa-sensei, so hearing that her sister would be staying the night was something she just couldn’t accept.

To be honest, I also found it hard to believe that sensei would obediently listen to her father.

From what I had seen back at their house, she was angry with him as well.

And she had to have known that saying something like this would upset Misaki.

Yet, she was still going along with it—probably because, as an older sister, she was genuinely worried about her little sister.

Misaki had been getting carried away with her emotions lately, and letting a high school boy and girl stay overnight together was undeniably risky.

It wasn’t strange for her to want to keep a close watch nearby.

Her excuse about “Dad told me to” was probably just a cover.

“No, you don’t get it. Dad’s been so worried about Misaki that he won’t listen to reason…”

“But he didn’t even talk to Raito-kun’s mother…!”

“Actually, he already did. Shirai-san’s mother was more than happy to agree…”

I see.

Misaki’s father was as calculating as ever—he had already taken care of things in advance.

Now that my mom had approved, there was no reason for us to refuse.

If we tried to, it would only make it seem like we had something to hide.

“Ugh…!”

Misaki pouted, puffing out her cheeks in frustration.

She had already been sulking because of me, and now this was only making things worse.

Meanwhile, Kokoa—still in sensei’s arms—was glaring at Misaki with clear discontent.

To her, Misaki must have looked like she was trying to stop her beloved Sasagawa-sensei from staying over.

And honestly, that wasn’t wrong.

…Well, now what?

At this point, with Kokoa so excited, sensei staying over was practically set in stone.

But Misaki wasn’t going to accept it that easily, and if this continued, Kokoa’s opinion of Misaki might drop.

That would be a problem for me, considering I planned to keep dating Misaki.

After all, it’s always best if your girlfriend and little sister get along.

…Alright.

“Misaki, I think having Sasagawa-sensei here might actually be a good thing for you.”

I placed my hand on her head and gently ruffled her hair, speaking with a smile.

In response, she looked up at me with teary eyes.

“Why…!? You just don’t want to sleep with me, so this is convenient for you, isn’t it…!?”

Her intuition was sharp as always, but she was too flustered to fully grasp what I meant.

The earlier conversation was probably still weighing on her mind.

“Think about it, Misaki. Who do you think is going to take care of Kokoa?”

Before I could explain, Sasagawa-sensei immediately caught on.

She smiled warmly, different from her earlier smirk, as if she truly understood my intentions.

—No, wait.

Was that her true goal all along?

Maybe she wasn’t just worried about Misaki.

Maybe she was staying over for Misaki’s sake.

The way her gentle smile radiated kindness—it almost felt like proof of that.

And now, I was starting to think that my mom had given her approval for the same reason.
