He just became the newly-crowned movie emperor when he died a tragic (actually, very stupid) death. On his way to cross the NaiHe bridge, he managed to evade Meng Po and not drink her soup. Thus keeping the memories of the life that he just had.

But he would never have imagined that he would be reincarnated hundreds of thousands of years later. In the Interstellar era! If it happened to other guys, they would definitely want to be a mecha warrior. Don’t most men dream of that at least once in their life? But sadly, that’s not for him.

There’s only one goal in his mind – to be the number one star in the Interstellar era.

With the knowledge and skills he got from his past life, he would definitely achieve it.

But who was this annoying person who kept on pestering him?

A certain prince smiled in a scary and crazy way: Cook food for me or else die.

A certain prince leaned over and moved his face closer: I don’t need food, I could just eat you.

The first time they met they had battled fiercely, just for a mere bunch of herbs. She needed it to save people, and he wanted to use it to save his own life.

“Let go of it, or you will die.” The man’s violet eyes were cold and sinister as he said in a low voice.

She held on tightly to the base of the herb and pulled its roots right out of the ground, before she turned her eyes back with a crafty smile. “It’s mine now. Snatch it from me if you can.”

When they met several years later they were no longer on opposing sides in hostility. In order to repay the debt for having stolen the herb back then, she went on to miraculously cure his body’s condition, relieving him of the inhumane torment that wrecked at his body day and night. He was amazed by the godly skills in Medicine she possessed and his heart went on to fall irrecoverably head over heels in love.

In the eyes of outsiders, Hyuga Yuuto is a genius in the traditional sense of the Hyuga family:

Tough, strong, gentle, and calm, he is a partner worth relying on at all times.

However, no one knows, in countless silent nights.

The young genius of the separation family stroked the caged bird engraved on his head and fell asleep with the sharp needle in his mouth, fearing that in his sleep he would reveal the madness and anger deep in his heart——
