Dear readers! Without any ads, maybe you will prefer .

Si Huaixi got bored while playing with zombies in the end times and picked up a novel.

The title of the novel is “Interstellar Heartthrob.” Si Huaixi thought it was a science fiction novel set in a peaceful era. But he had no idea it was about a strange ABO world. The men in it would actually have children?!

The protagonist is a male Omega who can have children !!!

Even more, the protagonist relied on hooking up with various rich and powerful Alphas, finally dominating the interstellar entertainment world.

Si Huaixi wanted to drop the book when he read it, and then he fell !!!

As a result, he became the cannon fodder, a gloomy 18th-line ‘Beta’ starlet, whom the protagonist hated, since his photos were popular on the Internet grabbing the protagonist’s limelight.

How can the cannon fodder who offends the protagonist have a good life?

It wasn’t long until the original owner was drugged and sent to the bed of an investor who enjoyed making short videos. Si Huaixi did not escape the drugging plot after crossing. But, he met a handsome Alpha by chance.

When he woke up the next day. Si Huaixi was surprised to find that the Alpha who spent the night with him was Pei Zhaozhou, the villain in the book!!! Strangely, the book’s villain, Pei Zhaozhou, was not furious. He pinched his eyebrows, smoked a cigarette, and let Si Huaixi go.

He thought the matter would end. But, Pei Zhaozhou suddenly came to the door one day and gave him the medical examination report. “I’m pregnant, and I need the company and comfort of the child’s father because of pheromone disorders,” he said, while slightly narrowing his eyes.
