I hear Alice is pregnant. I am asking because there is no pregnancy test drug in the world, so although it cannot be said to be definitive, it is probably definite.

That's why...

"Uh-huh, I don't make noises or anything..."

Instead of pillowing Alice's knee sitting in my room bed, I squealed as I pressed my ear against my stomach.

"Phew, I still can't hear you say that."

Saying it that way, Alice strokes my head lovingly.

In previous life, she died before she even made it. That's how I was born again to get a cute girlfriend and even make kids.

"I think I'm happy now."

"Hehe, I'm happy too. I'm so glad I met Lion in this world."

"Isn't that where you can reunite with your brother?

"Of course, I have that too. But Brother Yuya, who had pale thoughts in his previous life, and Lion's soul were just the same. It's Lion who likes me."

"... Alice"

That is to say, give up your first love and say you like me. It's a little complicated because they're both me... but I thought I'd be happy.

I liked Alice, too, before I found out she was my sister in my previous life.

Happy in this world with Alice and her children. To do this, there are a number of problems that need to be solved. The first is to say we haven't had a wedding yet.

It's not just Alice. Claire, hey. Sophia and I are both engaged, but we prioritize having kids with Alice, and we keep them in our custody, and of course we don't have a wedding.

Besides, I don't have to wait another year to have kids. Even so, the medical technology in Mule's city is needlessly lower than in Japan. As it is, we need to make haste in advancing our technology because we have trouble when our children get sick.

I need to do something... and I got up off Alice's lap.

"... Lion? What's the sudden matter?

"No, the..."

Alice is pregnant and has a lot of feelings. You shouldn't be talking about anxiety elements. I thought so and tried to deceive them, and they picked me out of the cheeks.

"... Yikes"

"Lion, you have nothing to hide from me. I know you think you don't have to worry about me anyway, but I'm more worried about that, right?

Even as I smile, I look somewhat anxious. He's right, he's worried about me.

... No, I can't. It's time to grow up.

"Sorry to bother you. We got engaged, but I thought we weren't having a wedding."

"Oh, yeah."

"Right...... you forgot?

"I haven't forgotten. I just thought Lion must have forgotten."

"Ugh..."

I actually forgot, so I have no objection. No, if you want me to make an excuse, that one at the engagement was too flashy, and I was going to have a wedding.

So I'm not bad.... No, I'm sorry, it was my fault.

"Weddings, are you going to mention them?

"Yeah, as long as Alice"

"Of course, I just... I have one suggestion to make"

"... suggestions? Of course, if it's Alice's suggestion, I'll consider it to the fullest."

"Then you're good with Claire and Sophia."

"Is that... good?

True, the engagement was with the three of us, and I swore I'd take care of all three of them. I prioritized Alice on the kid thing, but I'm not going to mess with the other two.

I'm glad you suggested the three of us together...... is it really good for you?

"Of course, it's good. Or are we good together? We owe it to both of us."

"Oh well... right"

When I first started out, I felt resistant to hanging out with my sister in my last life.

"But when it's a wedding for the four of us...... I feel like I have to be pretty flashy"

All three, celebrities in this world now. Even the declaration of engagement happened in front of the royal family. When the wedding feels cautious, they're going to say a lot.

Or maybe Alice's stomach will stand out not too far ahead.

"Well... talk to everyone around there, I guess"

I tried to wrap it up like that - but Alice smiled at me because she couldn't deceive me.

"Lion, you looked in a hurry earlier, didn't you? But if it's just about the wedding, you don't need to be in such a hurry, do you? Isn't there something else you're worried about?

"Mmm... Alice is sharp"

I sigh. I don't want to worry about Alice extra, but if this happens, it would be best to be honest with her.

"So, what's Leon worried about?

"Compared to Japan, medical technology is low, right? When my child gets sick, I want to be able to do something about it."

"Oh... haven't you been studying penicillin yet?"

"Yeah. Even on Earth, it seems it took about a decade to get practical"

I don't know how much you know the answer, but I don't know the process. It will take quite a few years to complete it in this world, which is far less skilled than the Earth at the time.

"Mm-hmm. I guess the only way to accelerate research is to improve the environment."

"Yes, but if I could do that..."

"You can do it, can't you?

"... Huh?

I saw Alice seriously in words I never thought I would.

"You were studying switched tattoo magic, weren't you? If you complete and improve that, you'll be able to apply it in a variety of ways."

"I see..."

This world-class magic is no less than the science of previous life. If everyone can handle it freely in the form of tattoo magic... they may be able to do things they have never been able to do before.

All right... right. Prepare for the wedding first. And let's do our best to improve the city's technical level in order to improve the environment when children are born.
