Superstar From Age 0 - Chapter 649:

The most famous deed of this princess was her words to her younger brother Liu Ziye.

When Yohan woke up in the morning, he had a beauty in his lap and in his bedroom. It was like a dream come true for him until reality struck him.

It was then he remembered that he had been cursed by a goddess in the game he had been playing before sleeping. In his sleep-deprived state, he had offended the goddess and as a result, he had been cursed to become a 'no-good' man who could only provide 'support' to the 'heroines' of this world.

Thinking nothing of that curse beforehand, Yohan went to sleep, only to find his world-changing from that day onwards. His normal and mundane life was no longer going to be as such as more and more fantasy creatures began to show up.

And a female voice awoke him with a notification
