My sister is a brother lover

Li Yun, who had lived an ordinary life for more than 20 years, would never have thought that not only was he not an orphan, but he was also the young master of the richest family!

His biological mother doted on him, and his biological sister doted on him brainlessly!

Lu Yun, who had risen from an ordinary person to the young master of the Lu family, was very worried!

His sister gave him a lot of pocket money every day. If he couldn’t spend it all, his sister would be sad!

Lu Yun, who could not bear to see her sister sad, could only spend money desperately...

But why was he spending more and more money?!
