Immortal Son-In-Law Returns

His eyes filled with complex emotions standing outside her house.
His ordinary life collapsed when he got into a relationship with the company's CEO. His life became a humiliation!
Perhaps, even the heavens took pity and allowed him to accidentally step into the world of Immortals where there was no law but only power. A strong could do whatever he wanted, and the weak would only die!
He did everything he could to survive, but who would have expected, just like he spent thousand years in that world?
When he finally managed to return, to his surprise, he found only five years had passed on Earth!
But after returning, what did he see? He had a four years old daughter. But she was treated like a burden and shame? Fury ignited his heart, but there was also an incredible delight!
Standing before her again, he swore all she lost because of him; he'll get it back. Get it back with interest included!
Only she and her daughter welcomed his return, while others started to scheme in the dark.
They didn't know it wasn't that trash son-in-law who had returned, but an Immortal son-in-law!
