[Three lives and three lives + two-way rebirth + male protagonist's amnesia + scientific research to save his wife + deep love and no regrets]
After resurrecting his life, Lu Jingxuan vowed to do only two things, not to be a dog licker, but to save his wife.
In his previous life, he licked the school belle Qin Ruomeng wildly for four years to no avail. It was only after graduation that he met the love of his life, Xiao Jinli. She suffered from a hereditary heart disease and stopped breathing in his arms at the age of 28. He spent hundreds of billions of his fortune to develop a life-saving drug, but it was too late.
When he was reborn as a freshman, he resolutely gave up the second female lead and actively pursued the female protagonist, working hard to make money just to conquer new drugs. But God's will played a trick on him, and the medicine failed again, and he watched her leave for the second time. Distraught, he pushed the drug to the market and saved countless people, but he died alone.
When I open my eyes again, it's registration day for freshman year again.
After losing a loved one twice in a row, the brain forcibly locks all memories. He began to chase Qin Ruomeng in a daze again.
Until that day, a girl named Xiao Jinli stood in front of him:
"Hello, I am your future wife."
"Are you sent here by Qin Ruomeng?"
"... You used to call me little koi."
She is also born again. In this life, it was her turn to run towards him.
