For Some Reason, My Ex-girlfriend, Who Lost Interest in Me, and My Current Girlfriend, Whom I’ve Known Since Childhood, Are Now Fighting Over Me

“HUH!? You want me to teach you how to win a man over!? What are you talking about, Big.
Sis?!”

My sister called me up because she wanted to discuss something with me, and I raised my voice in the coffee shop.

I never thought that my sister, who has made thousands of men fall in love with her, would ask me for such advice.

I was so shocked that I peeled my eyes open in astonishment, but in contrast, my sister sipped her tea gracefully.

I wonder what the woman who could create a painting just by sipping a drink was really talking about.

“You’re talking too loud, you playboy.
I’m gonna kill you.”

“Who’s the playboy!? I’ve got a girlfriend I’ve got my heart set on!”

“I don’t care what’s going on with my little brother’s bottom half.
Could you please refrain from being so vulgar?”

“This b***h…!”

I glared at my sister, who spat venom through her clenched teeth.

Well, it’s not the first time this woman has had a vicious temper.

My name is Kengo Ohashi.
I’m Natsukawa Shizuku’s younger brother.

The reason we have different last names is because our parents got divorced.

My older sister was taken in by our mother, and the younger brother, me, was taken in by our father.

So it’s been a while since I’ve seen my sister like this, but I had no idea that the reason she called me up was to ask me to teach her how to win over a man.

Who the h**l could have predicted that?

Well, I’m relieved to know that my men-hating sister has finally developed some feelings appropriate for her age.

“…So? What kind of a guy is he?”

“Yes?”

“As.
I.
Said.
I’m asking you who’s this guy you’re in love with?”

As a younger brother, I know better than anyone that my sister has a hardcore dislike for men.

And now that she has a man she wants to win over.
How could I not want to know?

“…Shota-kun.”

“Huh? I can’t hear you.”

“As I said, it’s Shota Komori-kun from my class.
Don’t make me say it over and over again.”

My sister looked away from me and her cheeks flushed.

Oh, s**t.
This is serious stuff, apparently.

It’s the first time I’ve seen my sister looking like a maiden, and as expected, I can’t even speak!

To be honest, just showing him her current state of embarrassment would be enough to get him hooked.

Well, it can’t be helped.
I guess I’ll just have to make it happen.

I asked, trying to keep a brotherly air in my heart,

“I can’t tell what kind of guy he is just by his name.
We go to different schools, you and I.
Don’t you have a picture or something?”

“Is the wallpaper okay?”

“Ohh…”

I didn’t expect it to be a wallpaper.
This Komori guy must have really messed her up.

I looked down at the phone that was held out to me.

There was a picture of a man on it that I couldn’t comment on.

I didn’t know a man for whom the words ‘normal,’ ‘ordinary,’ and ‘mediocre’ could be more appropriate.

“Um…”

“How’s that? Isn’t he a hundred times cooler than Kengo?”

“That’s definitely not true!”

I didn’t mean to say anything about other people’s looks, but my pride didn’t allow me to be inferior to this guy.

I’m not proud of my good looks like my sister, but I’ve never had a problem with women.

But that said, I have never played with a woman in my life.

“Ehh? What? Do you really think you’re better looking than Shota-kun? If that’s the case, it pains me to no end.”

“You know what they say, love is blind… So, what do you like about this guy?”

“I’m glad you asked.
So Shota-kun is–“

–Two hours later.

Machine gun talk went on and on from my sister, who normally doesn’t talk much.

In summary, my sister had asked Komori to be her fake boyfriend.

It was a measure that was typical of my sister, who was sick and tired of being favoured by the opposite s*x, and thanks to this, there were many stories that made me feel sorry for Komori.

I’m sorry, Komori.
As her younger brother, I apologize.
I’m sorry for my insolent sister!

But here’s the thing.

Apparently, my sister has really fallen in love with him while playing the role of a fake girlfriend.

My sister, who has never really loved a man before, couldn’t keep track of her feelings, so she acted coldly.

“I see… So whatever it is, you want to be a real girlfriend to Komori, is that right?”

“…Eh, yeah.
That’s right.
So please.
Tell me what I should do, Kengo.
You’re the only one I can ask about this.”

“…Well.
First of all, I think you should be honest with him and tell him that you want to end this fake relationship.
Then you can talk to him.”

“You’re absolutely right.
The first thing I need to do is tell him that I.
Want.
To.
End.
This.
Re.
La.
Tion.
Ship.
Right? Thank you, Kengo.
I’ll make sure to tell him tomorrow.”
