The time goes back a few months.

　Lula came to Cain's office with a large piece of paper.

'Master Cain, please look at this. I did my best!

　I look down at the paper Lula brought with her, which she says with her chest.
　There was a plan of the entire city drawn on it.
　The city is neatly demarcated, with parks and other facilities in places, and it is so well done that even Cain could not help but be impressed.
　All of the commercial districts are neatly demarcated, and some of the buildings are even drawn to look like shopping malls so that even small business associations can enter. The inhabitants are divided into several places to live, and even just thinking about it makes my cheeks relax.

This is my ideal city plan. It's the ideal city I've been thinking about since I was in Japan!　Let's do this.

　Although Cain was impressed by Lula's enthusiastic explanation, he wondered if this wasn't overkill as expected.
　Moreover, if we are going to build it as described here, we need a huge amount of money and not enough manpower to do it all.

''It will be fine. With Cain-sama's enormous magical power!　If we just let people handle the interior, it wouldn't cost that much, and we'd have more and more residents and more tax revenue.
'Yes!　Let's do it!
Thank you!

　It would be a good thing for the city in the future.
　The two of them convinced Alec to go ahead with it, and it was to be done.
　However, it was planned to take years to build, but Cain and Lula's bad temper exceeded the limit and they built the city in a few months.
　As for persuading the residents of the city, I threw the whole thing to Alec and explained and convinced him that we would make the shops and houses prettier than they are now.
　Since the city had many adventurers, the guild master, Rixetu, agreed, and there was almost no one to oppose it.

　However, the city spread out, and there was a large empty space in the center back.

''Lula, what's the space here?''

　At Cain's words, Lula smiled as she said, "I've been waiting for you.

'Let's build a castle here!　This is Lady Cain's castle. Since we will be hosting a princess in the future, I thought that's about as much as we need.
............ castle?
Yes, the castle. What else?　If we built the castle first, the residents might complain about it. That's why we put the city first.

　Then Cain and Lula proceeded to talk about what kind of castle they wanted to build.

'I'd still like a castle like the one in Europe. I saw one when I traveled abroad and it was very impressive.'

　Lula's words made Cain's imagination swell in his brain as well.

(If it's a castle, can you do it with the World Dictionary 《World Dictionary》? If you've made it this far, you can go to ......)

　And with Cain's boundless magical power and Lula's willingness to work, the castle was built without any weight of its own.
　Only the exterior boxes were created and the detailed interior was to be filled with people.

　Needless to say, looking up at this finished castle, they were both lectured by Alec.

　
　◇ ◇ ◇ ◇.

　
"Mr. Cain, ......, your father didn't tell you to weigh yourself down that long ago. ......?

　Cain scratches his cheek as Telestia looks drawn out.

''No, ...... just got a little fun, and I just had to .......
"I can't believe they built the castle "just by accident." ...... No one does that!
'Well, well, Teres, you don't have to say so much. You're going to live here when you get married, so why not?

　At Silk's words, Telestia's angry expression changes at once.
　Her expression becomes embarrassed and her cheeks turn red. She must be fantasizing about living in this castle.

''Gohon...... may I?''

　Alec, who was standing in line in front of the castle, called out to me.

'Welcome to Drintle. I'm the deputy, Alec von Silford. I have a room in the mansion (castle) for you today. It's only for one night, but please make yourself at home.

　Alec, who is crisp and greeting, bows, and the stunned teachers and students huff at the sound of his voice.
　And the female students can't help but look at Alec's face and their cheeks turn red.

''Please come this way.''

　A separate inn was prepared for the knights and adventurers of the escort and they were to be separated there.
　Of course, Claude said to me, "Cain, are you going to start a country? Needless to say, he was teased and patted on the head by Lina again.
　Led by the squire, the teachers and students are led into the mansion.
　The hall is vaulted and the ceiling is painted all over. The first time they saw it, the students expressed their admiration.
　Cain followed Sylvia as she led him around, despite the cold stares from the three of them.

''I came to the mansion to help out, but I was amazed at this castle.

(Don't call it a castle: ....... You'll get more and more suspicious.)

　Cain smiled bitterly and led the way to the three men's room.

''Cain-sama is in the back room. The rest of you will be in this room.

　I direct the three of them to a few empty rooms from Cain's room.

'I wonder what the rooms from here are.

　When Telestia asked in doubt, Silvia replied with a smile.

''This is, you see, ...... Cain-sama's wife's room, so no one will be staying here until then.
"? I'd love to see ...... such a thing, that they even have a room for us .......
'Your Highness and Lady Silk will both be married to Lady Cain in the future, and there's no problem if you just want to take a peek. Would you like to see it?　I'm not allowed to stay at the quarry yet, but .......
I want to see it!

　Sylvia's words bite them both.
　They unlocked the room and led them inside, where they found a large bed, a vanity table and even a sofa.
　Each room also had a toilet and a washbasin, which made the three of them gleam in the eye.

'Wow!　Such a gorgeous room: ...... ugh.
Thank you, Mr. Cain!　I'd marry this one in a heartbeat.

　They look satisfied. But only one of them bites his lip.

(It's not fair ....... I would have gotten to know Cain sooner than you did ....... (It's the only time I resent Byssus' blood.)

　Although she didn't show it on her face, Riltana felt envious of the two of them.
　No one noticed such a thing and Sylvia's guidance continued.

''This will be the room for your wife. Also, there's only Cain-sama's room at the back.''
"I want to see that too!

　Sylvia gave Cain a look. Thinking she had no choice, Cain nodded, reluctantly.
　When you open the massive double-ended door, you'll find a reception set, a desk for office work, and further back - a bed large enough to hold several king-sized beds.
　There's probably enough space for about ten people to sleep.
　Even Cain thought it was overkill, but Lula said, "This is about as normal as it gets! He was the most enthusiastic about finishing it.
　It was comfortable, yes, but it was so big that it felt lonely to sleep alone.

It's ...... awesome ....... It's probably more luxurious than your father's room .......
Here's the future: ......

　Both of them had their cheeks stained with the future in their minds.
　Then Riltana said something unexpected.

'Cain-sama ...... you have quite a bit of room for your wife, don't you?'

　With those words, both Telestia and Silk froze and were pulled back from their fantasies to reality.
　They began to count the number of doors that lined the corridor.
　Indeed, there were about ten rooms secured on both sides of the corridor.
　Then their gazes focused on Cain.

''Or, Cain-sama ...... could it be that you are going to take ...... this many marriages?''
Mr. Cain, you're not really going to tolerate ten people, are you?

　With a cold stare, the two men crowded up to Cain.

'I might possibly--'

　Riltana, whispering behind them, smiled and her cheeks colored with a smile.
