The Kai family - he is from a very rich family, his father Don Rongle is very serious and does not like it when he is contradicted,
Everyone knows that Kaz and Kazu are like brothers, but in reality, it's not that simple: Don Rongle has two sons, Noah - the eldest son (39) and the youngest son, Kai (20). Noah already has his own family: his wife, Aisha, and his son, Kaz, who is also 21. It turns out that Kaz is Kai's nephew, but it's hard to explain to someone that Kai is Kaz's uncle, so they simplified things and told everyone that they were just brothers.
