Chu Yingzhi is the top in a danmei novel. Unfortunately, he was born without the ability to feel emotions, and somehow turned a sweet romance into a business-warfare story with no romance at all.
Later, he transmigrated into a book and was bound to a System.
The original character was recognized as the strongest cultivator in the cultivation world. He appeared to be a cool, beautiful man, but was actually psychologically twisted. He would physically abuse and torment the future villainous Demon Lord, unable to win his love.
Once the villain became the Demon Lord, he would take savage revenge on the original character, leaving him dead without a proper burial.
The System advised Chu Yingzhi to comfort the villain while he was still weak and pitiful, and become the person he cherished most.
The emotionless Mr. Chu thought for two seconds, then had the villain bound and brought back ahead of schedule.
System: I've seen people who don't care if they live or die, but I've never seen anyone as reckless as you!
Chu Yingzhi: Your fate should be in your own hands. He's locked away somewhere this dark, without a ray of light. How could he still become the Demon Lord?
Later, when a man wreathed in demonic energy held him captive in his arms and he was powerless to fight back, Chu Yingzhi was confused.
Which step had gone wrong?
At his most desperate moment, someone reached out a hand to Yu Zhiyao. He looked up and met a pair of cool, distant eyes.
During the days he was locked in the dark dungeon, he didn't think about how to escape. He thought about how to make those cool eyes fill with tears.
"I don't care how blinding the sunlight is. I only want to seize him and make him mine."

Theme: No matter how difficult things get, never give up easily. Have the courage to tell fate no.
