MTL - Best Son-in-law - Chapter 3006 completely changed

Rudel Arses, the first born of one of the ‘Three Lords’ of the Courtois Kingdom, is from a corrupted family, but at 5 years old, he saw a dragon in the sky and his dark future as a villain changed. He was considered an idiot, but was that true? How would his effort to become a dragoon change the kingdom?

Thank you for your support~
My name is Toru Kurosawa and I am 25 years old.
I have another name, Toruya Karasuma, because there is a mysterious old man in the family, and for some inconvenient reasons, I personally don’t like to use this name.
Now I just returned to Japan from Italy, and my first stop decided to visit the industry I was planning to retire, a cafe I bought before I left the country. The name seems to be Poirot?
Even though when I was 18, I went to Italy to study abroad for seven years because of my rebellion, and was called back by an inexplicable phone call to inherit the family business, it did not change my dream of running a coffee shop!
Think about it, you don’t have to wake up early and wake up naturally every day, sit in your own coffee shop and drink a delicious latte, and you can study recipes when you have nothing to do. What a wonderful life!
As for groups and organizations?
The manager’s salary is so high, don’t you want to do it if you don’t manage the group well for me?
Who would want to accept an organization that has been turned into a sieve by undercover agents!
Stepping into Poirot, he looked at a certain blond, dark-skinned person who seemed familiar to me to say hello. I pondered: Will the salted fish life I want come true?
Brother help! I am surrounded by red squares!
