After Being Betrayed by My Girlfriend, I Kiss Her Little Sister - Chapter 4

An Inconvenient Truth (2)

“Let’s have dinner outside. There’s a restaurant I want to go with you, Kanata.”

“…eh, if that’s the case, you should’ve just told me so earlier. I was so nervous the whole time, thinking it’s something serious.”

“Fufufu. Ah, that’s right, thanks for lending me your jacket. Aren’t you cold, Kanata?”

“It’s fine…I’m not cold.”

“Okay…”

I can’t just leave a girl wearing only a hoodie in this weather, so I lent her my jacket. But it doesn’t fit her. My jacket is too big, Hina’s sleeves had turned into moe sleeves.

(TN: Moe Sleeves is when a person wears an oversized jacket or hoodie and the sleeves are longer than their arms)

She’s really cute…

Well, she’s a girl, so of course there’s a height difference…

But compared to back then, it doesn’t feel like she’s grown much.

“Hina.”

“Yeah?”

“How tall are you?”

“I’m… 154 cm!”

“You’re short.”

“W-What…? Sorry for being short! Hmph!”

“Sorry, sorry… But I think you were 152 cm back in middle school.”

“I’ve grown two centimetres! Two whole centimetres! Don’t ignore that…”

“Yeah. You’ve grown…”

With that, Hina brings us to a family restaurant that is trending on social media.

Kisaragi once told me about this fancy-looking family restaurant, and now that I’m actually here, I can see why—it’s really beautiful.

I’ve heard somewhere that the atmosphere of a place is just as important as the food, and I guess that’s true.

Besides that, the prices are super cheap! Now I get why it’s so popular.

“Let’s go, Kanata.”

“Yeah.”

Hina says so and suddenly pulls up her hoodie on.

Pulling up her hoodie just to enter a family restaurant?

I tilt my head in confusion.

“What’s wrong?”

“……”

Without saying anything, Hina takes my hand.

Just like that, she leads me to our seats.

“Hahaha, Kazuma-kun, you’re really funny~”

Just as we sit down, I hear Umi’s voice from behind us.

She’s here with some guy I don’t know…

The guy sitting across from her—could he be the one who hugged Umi at that time? I’m not sure.

The only thing I know for certain is that Umi is having dinner with a guy I don’t know.

“Umm…I’ll have this and this please.”

While Hina is placing her order, I can’t stop thinking about Umi.

Then, I hear Umi’s laugh again.

I know this is wrong, but I shut my eyes and listen to the conversation coming from behind me closely.

“By the way, it’s a White Christmas, and you’re not spending it with your boyfriend? You were with me on Christmas Eve too.”

“Hahaha! But I have more fun being with you, Kazuma-kun. I totally forgot about Kanata-kun. It’s fine, it’s fine~ I told him I’m busy today, and besides…Kanata-kun is way too serious, so he’s boring~”

“Hahaha, if Kanata heard that, he’d be really hurt, you know, Umi-chan?”

“Eh~ But it’s the truth. I’ll just call him tomorrow and say, ‘Sorryyy~♡’ I’m sure he will say ‘It’s okay’ right away. Kanata-kun is such a simple guy anyway, he won’t get upset about something like that. Ahahaha.”

“That’s mean! Hahaha!”

“Yeah, he’s just in the way~ Such a bother~”

I keep listening to their conversation.

Why…?

Why would Umi say something like that about me to a guy I don’t even know?

Calling me boring, simple-minded…there is nothing I can do right now. We’ve been together for a whole year, why is Umi treating me like a nuisance? I really don’t understand.

Umi always has a gentle smile on her face in front of me…but behind my back, she is secretly badmouthing me with a guy I don’t even know.

“Umi-chan, what do you want to do after we eat? Want to come over to my place?”

“Winter break starts tomorrow, so there’s no need to rush, right? I want to go to a hotel again tonight~”

“Sounds great. Ahh, poor Kanata…not being able to spend Christmas with his girlfriend. But oh well, can’t be helped. Umi-chan is really cute, after all. I’ll make sure give Umi-chan lots of love in Kanata’s place. Hahaha!”

“Fufufu~♡”

I can’t take it anymore. Before I knew it, I’m clenching my fists tightly.

At that moment, Hina who is sitting across from me, reaches out and holds my hand.

“Hina…”

“Are you planning to hit him…? Don’t do anything right now, Kanata…please.”

“Why…? Why is Umi here…?”

We talk to each other in hushed voices.

“I’m sorry.”

Could it be that Hina knew all along? Could it be that Hina knew the two of them will come here? Is that why she didn’t tell me where we’re going before we left the house? When she mentioned about Umi’s cheating earlier, was she just trying to confirm whether I already know or not? Was that it? My mind is a mess, I have no idea what to do.

Then, I suddenly remembered what Hina said earlier, ‘I don’t like lying to you, Kanata.”

No matter how I look at it…this is definitely cheating.

The truth is, I already know that Umi is cheating on me.

And yet…I keep trying to deny it.

The moment I saw Umi hugging another guy, it should’ve been obvious. But…I’m too afraid of being abandoned by her. So, I’ve been running away from the truth. And Hina…she brought me to this restaurant to make me face it. Because seeing it with my own eyes is faster than just hearing about it. There is no way I can claim ignorance anymore.

This is, without a doubt, cheating.

“This is on you, Kazuma-kun?”

“Of course. Ehh? don’t tell me…you actually split the bill when you go on dates with Kanata?”

“Ehehe…”

“Man, that’s just sad. Well…I guess that’s just the best he can do, huh?”

Damn it…

“Umi-chan is a cute girl, so she deserves to be treated accordingly. Any guy who can’t do that…should just get out of the way. Right, Umi-chan?”

“What’s with that~? Haha, that’s hilarious!”

“Hahaha, shall we get going?”

“Yeah!”

Saying so, Umi links arms with that guy.

All I can do is stare at her back as she walks away.

“……”

Thanks to the hat I’m wearing, those two didn’t notice me…I have no choice but to face the truth I’ve been desperately trying to deny.

I heard it with my own ears. I saw it with my own eyes.

Right now, I’m doing my best to hold myself together in front of Hina.

I feel like I’m about to burst into tears at any moment, but I have to hold myself together.

It hurts. It hurts so much that I can barely breathe…it’s devastating.

“Kanata.”

“……”

“Kanata…”

“Yeah…”

When Hina calls my name, she looks like she’s about to cry, just like me.

“Let’s eat first. We can talk while we eat…Kanata.”

“Yeah.”

“I’m sorry…”
