my billionaire uncle

I don't think so. 'My Secret Billionaire' sounds more like a fictional tale. Stories like this are crafted to draw in the audience with interesting plotlines and characters, rather than being true accounts.

An uncle-in-law refers to your father's brother-in-law or brother-in-law. So if your uncle-in-law is your father, then he is your father's brother or younger brother.

Your uncle is your father's brother-in-law.

In many novels with such a title, it could follow the journey of an ordinary person who stumbles upon the hidden world of a billionaire. For example, the protagonist might discover a secret business deal or a family mystery related to the billionaire. This discovery could then lead to a series of events that change their life, perhaps through newfound wealth, power, or love.

No, it's not. 'My Secret Billionaire' is a fictional story created by the author's imagination.

An uncle referred to the husband of his father's sister. He could also be called an uncle, an aunt's father, or an aunt's father.

My uncle is my father's brother-in-law or my father's sister-in-law.

My uncle is a soldier, and he's also the person I admire the most and have the greatest influence on me. His uncle's family was from the countryside. He had suffered a lot when he was young, but after he became a leader in the army, he never regarded himself as a "leader". He always did what he asked the soldiers to do first. Last year, his uncle participated in the military competition, but a few days before the competition, he was accidentally injured in training and had several stitches in his head. At that time, everyone advised him to give up the competition, but he still insisted on participating in the competition with his injury and achieved the good results of the military region's all-around first place. I admire uncle's strong will and his spirit to challenge himself. Uncle often tells me stories and teaches me the principles of life. Uncle is very good to me, but sometimes he is very strict with me. I remember one time when I went shopping with my uncle. I thought he would take a taxi, but he led me to take the bus. He even told me not to waste money if possible.

I don't know for sure since I haven't read it. But it could have a protagonist who is an average person, like a young journalist or a struggling artist. And of course, the billionaire would be one of the main characters.
