After finishing their meal, Bastien thought for a moment and asked Kai with a serious expression. "So, are you going to start or do you want me to start?"

Kai understood what he wanted to say and nodded. He politely lowered his head and said politely. "I would like to ask Sir Bastien for Sofia's hand in marriage. I know that I'm asking much, but I can't really do anything for three years from now.

"I can't say anything about the reason, but you can say that this entire world is in the middle of the sea, waiting for the big storm to come." Kai's expression was serious and his tone was severe.

"You know something we don't know?" Bastien frowned and realized something. "Your government know about this as well?"

"No. It's only me." Kai shook his head. "Well, maybe my teacher knows about it too. But all the main matter, I'm the only one."

"Ahaha, it seems that our soon-to-be son-in-law has been battling something that we don't know. I think I need to thank you." Regine was humming with a smile, fully believing what he said.

"You believe me?" Kai widened his eyes in amazement. This could be easily interpreted as a lie because this was the only thing he knew.

Regine also understood that, but she explained. "Lie or not, I know that you indeed have something important. The moment you know about the talking magical beasts you called Protectors, that's the only thing we need to know. After all, I'm sure they are related to this.

"Unfortunately, when your government and even your teacher don't know much about this, I'm sure that we're not supposed to know it either, but if you need any help, just call us. Although we consider things for the union most of the time, we are still fighting for humanity.

"That's why you don't need to worry about the date. Your promise alone is enough for us. Besides, you are underestimating your position too much. I don't know if you have realized it or not, but the moment you speak one thing, the whole world will know about it. You can easily raise people's opinions to protect yourself or attack someone. This is the importance of your words." Regine explained clearly with a smile.

Kai was taken aback by that response. When he heard about Sofia's grandfather, he thought he needed to argue with them, but it turned out that her parents were so reasonable.

"I think my wife has said everything. I will only add two points. First, I don't care about your problem, but we can't govern a place without its citizens. The only reason why humans can unite is because they have a mutual enemy. Hence, call us when you need help. Of course, we won't stretch our hand if you're trying to have your revenge against the Katsuragi Family.

"Second, I don't like a break up. I'm sure that someone like you must have considered everything and committed to your own promise, so I will watch over your relationship until both of you are ready. Even though I don't have multiple wives for various reasons, I don't condemn it either unless it's too big.

"I mean, come on, you're expecting me to say that you will give everything to your wives when you actually have ten or more? I can't believe something like that. The family will be messy sooner or later when you have a child and you need to apply your strength to make your own words heavier.

"I don't wish to see such a toxic family. Since you have your own problem, I will try to assist you in any way you can. After all, the son-in-law is the father's greatest ally that will make his daughter happy. That's why I welcome you as Campbell's family son-in-law." Bastien smiled.

Sofia also made a big smile when she heard her father and mother talking. This was a unique family since she had an unreasonable but adventurous grandfather, a firm and calm father, and a lovely and caring mother.

"Right… I would also like to thank you since Sofia has grown up a bit because of you. I was worried that she would turn like her grandfather, but it seems love indeed can change a person." Regine smirked, teasing both of them.

"Indeed. Even visiting you was just her own whim. She wanted me to process everything for her. Haiz, looking back now, I can see why I'm always smiling recently." Bastien facepalmed and shook his head helplessly.

"You don't need to add that detail, right?!" Sofia shouted, feeling embarrassed.

Kai smiled and enjoyed this atmosphere. They then discussed various matters regarding the family, EU Base, US Base, and their relationship.

It was just a light talk, but both sides could learn from each other pretty well. As one would expect from Bastien, he always shut his father up, not letting him talk nonsense to Kai, unlike Michael.

Unknowingly, the sun was about to set when they finished their talks. It just showed that the talks were both important and interesting.

Even Regine became more spirited to challenge herself in the kitchen again, while Kai ended up taking a bath with both Bastien and Jules, talking about a few things in a relaxing bath.

Not long after, they had dinner before Bastien brought him a few things.

It was his uniform for the academy. It was a set of a smooth white shirt with a simple logo on the left chest. On top of the shirt was a white vest to make it more elegant, especially with few golden stripes on the sleeves. The pants were white without any things on them. It seemed they needed to wear gloves too, but other than that, he didn't see any strange things to be worn.

"This is your uniform for school. There are a few things you need to do in school and understand them, so I will leave them to Sofia tomorrow."

Kai took the uniform and nodded. "I understand. Thank you very much."

"No need to be so formal. You should try to take a rest first, though, I know that you are not tired." He laughed. "Anyway, because your departure was last minute, you will need to go to school tomorrow since it was already started two days ago. I can't really hog you all the time, can't I?"

"Yes. I will try to rest my body."

"Then, Sofia, I will trouble you to guide him."

"Okay, Father." Sofia gently nodded before stretching her hand to the door, asking Kai to leave with her.

Looking at them leaving, Bastien's face mellowed before closing his eyes. Suddenly, his wife came closer as he pulled her into his embrace. "We don't need to worry about her anymore, right?"

"Yes. She has grown and someone can take care of her better than us. We only need to get our son a wife." Regine smiled, albeit that smile soon disappeared as she noticed something. "That's right. Where's Father?"

"Eh? He is with us just now…" He turned around and didn't see a single person other than them. It was at this moment the two realized that Jules once again wanted to do something. "Ugh. Your father-in-law is annoying."

"No, no. He is your father."

"Whatever. I will drag him back to this room in this instant." Bastien released his magic power as he walked out of the room.

Meanwhile, Sofia and Kai had arrived at the guest room… or it was supposed to be a guest room, but the only thing he could see was that this was someone's room.

The king-sized bed had been arranged for a couple to use. Next to the bed was a dressing table where he found some makeup on it. Although the room was plain, he noticed the sweet smell that seemed to be the same as Sofia's.

"Ehm… Don't tell me. This is your room?" Kai blinked his eyes a few times before glancing at her.

"Yes?" Sofia smiled and closed the door, locking it so no one could bother them. "This is fine, right? You feel reserved to do it back in the US Base because the others are there, right? I have talked to them about this as well, so I know."

"…" Kai fell silent, watching her expression wrenched in pain. She must have been holding back for a long time and as she said, he had been holding back because he wondered how to break the news to them. "I am sorry… for everything."

"It's fine. I can understand." Sofia shook her head.

"But…" Kai was about to say something, but Sofia already knew what he wanted and closed his mouth with a kiss. She then walked to her dress table before taking out two tubes filled with medicine that he was familiar with. "That medicine…"

"After talking to them, they gave me this medicine. It's to prevent pregnancy and to hold the Zodiac Blood from coming out, right?" She smiled and handed one of them to him.

Kai was stunned as he never expected that they had been doing this behind his back. But when he took another look at the incident, it was truly his fault. Still, this was something special, so he didn't want to do it because of his mistake.

Instead, he made a little smile and patted her head before gently lifting her chin to face him. He took medicine and drank it in one go.

Seeing this, Sofia also drank until the last drop without hesitation.

The two smiled at each other and kissed.

Their long passionate night just started as Kai later became "tired" and completely forgot about his jet lag.
