There are times when you’ll still never be good enough no matter how hard you try.

Born with a frail twin sister, Li Caiyi gives most of her time to take care of Li Chunhua. Her parents and older brother trust her to take care of her sister, yet Li Caiyi can’t help but feel the disparity in treatment and affection given to both of them.

In her whole life, she has never become anyone’s first priority. Not in the heart of her family, and especially not in the heart of her childhood friend, the Young Master of Meng family, Meng Renshu.

When Li Caiyi became Meng Renshu’s wife, Li Caiyi thought she could finally become someone’s first priority, but everything fell apart in just three years.

She decides to let everything go. Then she meets Shen Qiang in the most unexpected place. No one wants to accompany her in her life, yet this stranger offers to accompany her in death.

“Do you want to jump together?”

When she opened her eyes, Li Caiyi had gone back to her high school times.

This time, she won’t make the wrong choice again.

But where can she find Shen Qiang?!

Xiaya reincarnated in the Dragon Ball Universe as a Saiyan 12 years before the destruction of Planet Vegeta.

Watch him as he creates the strongest legend of Dragon Ball World from the beginning.
