After Traveling Through The Books, I Became The Villain’s Yaron

An optimistic and cheerful medical student is brain-attacked by his gloomy and decisive father in love. After being struck by lightning, Shen Xuzhao transformed into the vicious male partner of the same name in the novel that made him so angry that he had insomnia - a precious dragon that has not yet broken out of its shell.
According to the original work, he should have chosen Jinlong Yuchiyan, and then he was left out, looked down upon, and finally died miserably. What upset him the most in the whole book was the powerful but lonely black dragon Wen Shuming, who was scarred and had no choice but to die alone due to mental violence.
Come to the beginning of the story, where Dragon Lair chooses its mate.
This time, Shen Xuzhao did not hesitate to wrap his mental power gently but firmly around the gloomy and scarred mental power in the corner.
The entire dragon's nest fell into deathly silence.
Wen Shuming stood stiffly on the spot, his heartbeat frozen for thousands of years deafening for the first time.
Later, the dragon clan discovered that the once gloomy and violent black dragon, shunned by all dragons, had changed. He carefully held the little Yalong in his palm, clumsily learning to be gentle, suppressing all the sharp edges, and willingly bowed his head.
Later, when the protagonist, Gong Shou, was entangled in a bloody sadomasochism, Shen Xuzhao was comfortably nestled on the sofa, swinging his legs and commanding: "I want a raw cake."
But Mr. Wen, who was rumored to be ruthless and in charge of a huge business empire, was wearing an apron at the moment, seriously comparing human recipes, trying to make the thousand and first burnt cake sweeter.
——Time traveling is not for the plot, but for picking up a big black dragon that no one wants.
"The heavens and the five human beings record the mingling, and it will shine like the sun and the stars for eternity."
