Jonathan was in high spirits and suggested taking Aaron out for a good time, saying he wanted to show Aaron the customs and culture of Spain as a way to celebrate their collaboration.
He actually wanted to take Yoselin out for some fun and introduce her to his subordinates as their sister-in-law.
Aaron belongs to the group of people who are considered "big fish in a small pond." No matter how impressive he is in his own country, he has to be humble here. Therefore, when Jonathan is willing to show him around and have fun together, Aaron is naturally delighted.
Thank you again and again, with a humble and respectful attitude.
This is also Aaron's true nature; he can always put himself in the right position, never making others feel disgusted.
