Young Master He had always been a male god in the eyes of others.

Until one day, the god-like him died.

And he became the much detested white silk trouser-wearing second rich generation.

Male God He was unaffected by this.

In his previous life, he had sacrificed everything for his clan, now, he could finally break free from that tiring life.

The only thing was that he had gained a handicapped partner.

Initially, he thought his partner was just a weak, gullible and pure lamb.

In the end, a certain person changed entirely making everybody cry and shout daddy.
