I am Sawa Tono . Just an ordinary woman. By the way, I'm in my thirties.

I have a younger sister named Sana, who is four years younger and has a boyfriend. If they end up together, she will become Sana Wakai.

However, I oppose my sister becoming Sana Wakai.

It's not that her boyfriend is a bad person. He has never switched partners around, he's not drowning in alcohol, and he doesn't get violent.

What I'm concerned about is the flow of events leading up to my sister meeting and dating him.

Originally, he wasn't dating my sister; he was dating her childhood friend.

My sister and her childhood friend have been close for as long as their ages match, and they know each other so well that they can recall each other's height and weight down to the third decimal place.

Despite their close relationship, my sister apparently didn't like that her childhood friend was dating him. So, during an outing with the three of them, she turned her childhood friend into the villain, causing a breakup, and subsequently, she started dating him. In other words, her current boyfriend was taken from her childhood friend.

I'm just a bystander and have never been in a relationship, but I think it's quite wrong for a family member to frame her childhood friend as the villain.

However, when I shared this with my friend (who's good at romance), she said, “If you want to win the heart of the person you love, it's understandable to betray your friend. No one can stop a passionate heart.”

There may be some truth to that, but it's outside common sense. It's acceptable to choose romance over friendship, but it's wrong to do something that would sever a friendship.

Maybe this is why I have been single for as long as I've been alive. However, this is my sense of justice. I am convinced that this is the right way.

Furthermore, it's not that I'm opposed to dating someone taken from a close friend; I'm just worried.

I'm concerned not only about the relationship with her childhood friend breaking down but also about her possibly seeking revenge against my sister. Although the chances of that happening are low, it's not zero.

And I believe, though it may come off as imposing, that only happiness obtained justly is happiness that one can genuinely rejoice in. Happiness that comes from making someone else unhappy feels like miso soup with sand mixed in.

Having written at length about my thoughts and old-fashioned values, I find that they have gone off to choose rings for their ring fingers.

They are thrilled to be with the person they love, and right now, they have nothing but enthusiasm. They have even lost their rationality.

Moreover, this whole situation was conveyed to me just yesterday. These two, filled with nothing but zeal, reported this to me as a “post-facto announcement.” I wish my sister wouldn't treat this like just another casual conversation.

Well, because of this, although I had time to worry, I didn't have the chance to convey my thoughts to them.

However, just as they returned home excited, we received some shocking news. It seems that my sister's childhood friend has gotten together with a young elite (an important person) from a major corporation.

It feels like it hasn't been long since my sister took away her boyfriend, but it seems that those in love have some untapped energy in their actions.

That said, I feel relieved knowing that she has obtained a big happiness in a just manner.

In the living room with just me, my sister, and her boyfriend, we all widened our eyes as we looked at the glowing screen that delivered the news.

Upon hearing the news, my sister exclaimed:

“Haa!? If I had known this would happen, I shouldn't have just taken a slightly better guy from her!”

And just like that, she started to reveal her true feelings in front of him.

My sister finally exposed her true self.

I felt sorry for him when I thought about the situation. However, I also believed that he wasn’t entirely innocent in choosing someone like my sister… after all, she was his ex-girlfriend’s childhood friend after all.

He had no idea about the whole “stolen” situation, and as he caught a glimpse of the true side of her, he instinctively began to distance himself.

“Wait a minute, …Sana-chan…?”

My sister froze with a look that said, “Oh no, I messed up,” while he, disappointed and disillusioned after discovering her true feelings, lost trust in her.

Had he already bought the ring? From the way he seemed so excited, it felt like something had been decided.

What would happen next?

Being a reasonable person, he would probably break up with her.

Since he was just “a slightly better guy,” the breakup might not hurt my sister too much. However, the experience of this blunder would leave a significant mark. It would spread as a rumor and reflect on her reputation. Well, it was her own fault.

Turning slightly to face my sister, who couldn’t respond, he said in a low voice:

“Sana-chan… no, Tono-san. Please refrain from having conversations or contacting me for a while… no, just don't.”

With that, he left.

All that remained for my sister was a sense of loss.

I sighed and quietly passed by my sister, who was frozen in place, leaving the scene.
