I’m Dating My Ex-Girlfriend’s Older Sister, and We Have a Great Chemistry So Everyday Life Was Fun - Chapter 19

“……You’ve been studying really hard.”

One day, there were only two days left before the final exam.

I was studying for the final exam at the same pace as Rina san when Yuika spoke to me.

Due to an incident at a family restaurant, although we have a delicate relationship, it’s not like we’ve been insulated from each other. 

We are more than acquaintances, but less than friends.

“Well, you know. I want to get good marks.”

“Hm.  ……I see.”

The conversation was not interesting, so I continued to look down at my reference book.

Yuika put her chin in her hands and gazed boredly out the window.

★

The final exam is over.

With Rina san’s help, it was the biggest effect in my history.

“51st, huh. ……On the contrary, that’s amazing.”

The result was I was placed 51st in the grade.

I just barely made it to the top 50 line.

It’s a school for advanced students, so it doesn’t seem to be an easy barrier that can be overcome in a few days.

However,

“I would rather give up if I was 80th or something like that…”

If I hadn’t made any careless mistakes, I would have made it to the top 50.

My frustration was doubled because of that.

Above all, I didn’t try hard enough, so I didn’t even talk about my past with Rina.

As I slumped my shoulders in disappointment, Rina san smiled.

“Takuto kun, I know you worked hard, and I’ll tell you about the past.”

“Eh, Is that okay?”

“Yeah. There’s no point in hiding it.”

Thank God.

I thought she was just going to brush it off.

However, Rina san raised her index finger.

“But”

“B-but?”

“If you listen to one thing I’m going to  say from now on.”

“Etto, What should I do?”

Rina san put her finger on the tip of her chin and smiled softly.

She whispered to me from her light pink lips.

“Kiss.”

With a thump, my heart made a sound I didn’t know it was capable of.

It’s just two words.

But they were more than enough to break my thoughts.

“W-well, that’s…..”

“It’s been about three weeks. Since we started dating.”

The dating period has been increasing steadily.

Perhaps because of the final exams, I feel like the time is going too fast.

However, it’s true that three weeks have passed.

Is it okay if we do it soon…?

“Rina san, are you sure? I-I mean, I’d prefer a more memorable situation for my first time.”

I swallowed my saliva and cut in fearfully.

Rina san’s first boyfriend was me.

Naturally, this would be our first kiss.

The current location was Rina san’s room.

It’s not that it’s an inappropriate place for a first kiss, but if it’s for the first time, I think the situation should be more elaborate-

“Eh? Oh, no, it’s not the first time I’ve kissed someone.”

“Eh?”

“Like I said, it’s not my first time. I’ve kissed someone before.

“Eh, wait, a-are you lying?”

I asked pathetically, while feeling agitated.

I have no intention of digging up things that happened before we started dating or blaming each other.

But still, I can’t help but imagine things I don’t want to think about.

Kuh…….

Am I so narrow-minded?

“‘It’s no use lying like this. I already gave my first kiss.”

“L-like you gave it to your father? I don’t think you can do that with family members.”

“Nope. It’s to the boy I like.

“…..I see.”

I gradually lose my spirit and draw a lot of vertical lines while feeling depressed.

I never thought I would be so shocked.

Well, at least, I’ve kissed Yuika before.

It’s not right for me to wish that this was the first time for Rina san.

Damn, I just got so pissed off…….

“Hey, won’t you kiss me?”

“…..I will. I’ll overwrite it.”

I wonder which bastard stole Rina san’s first kiss.

I think it’s probably a story from her elementary school days.

I can’t help but think about it.

I put my hands on Rina san’s shoulders.

“Even if Takuto kun kissed me, I don’t think it will be overwritten.”

“I-it’s just a matter of feelings.”

“No, it’s not like that.”

“……?”

I don’t understand what Rina san is saying.

“Well, I’ll tell you about it later.

“Sigh.”

While I made a confused face, Rina san gently lowered her eyelids.

She looked calm, but her face was bright red. Red from the ears to her neck.

Even if people say she’s on a different race, I’m convinced by her skin tone.

I made up my mind and brought my face closer.

My heart is racing.

But in times like this, I mustn’t be afraid.

That’s why, once again, I mustered myself up and closed the distance to zero.

Our lips made contact.

Rina san’s lips are stiff, perhaps she was nervous.

But as we continued to make contact with each other, Rina san’s shoulders lost its strength.

We’re just touching each other.

As expected, I can’t do more than that yet.

As my heart was gradually filled.

Rina san folded her hands behind my neck and came even closer to me.

Oh no…….

If I go any further, my rationality will …..!　

Hm?　

I’ve had this feeling before-

I remembered that I was completely out of oxygen.

I pulled my upper body back and interrupted the kiss.

“Isn’t it too long?”

“Because Takuto kun didn’t stop kissing me.”

“Rina san didn’t let me stop.”

“I don’t think it’s good to put the blame on me like that.”

Rina san gave me a fishy look.

I covered my mouth with my right hand to hide my blushing cheek.

“Oh, By the way, that.”

“Hm?”

“As I thought, I might not need to hear about the past after all.”

“Eh? Is that okay?”

“Yeah, because I remember.”

That’s right, that was when I was in the fourth grade……
