He is the adopted son of the family, with a humble background but an arrogant personality.
He is a peerless man with both appearance and martial arts skills in the human world. He is arrogant but extremely lazy.
They belong to the same family but have never met.
Until that day, he used him as a shield to avoid the marriage proposal from the Supreme Lord of the Demon World. His words, "He is the person I want to grow old with," accidentally contributed to their rapid and inexplicable marriage.
On the actual wedding night, he still couldn't believe that he was actually married to this peerless man who was known as "the most beautiful woman in the human world".
But who knew that once this marriage was formed, it would truly last a lifetime.
