Three Lives, Three Worlds, Never Letting Down My Little Koi

[Three lifetimes + both leads reborn + male lead loses his memory + scientific research to save his wife + unwavering devotion] Given another chance at life, Lu Jingxuan swears to do only two things: stop chasing women who don't love him, and save his wife. In his previous life, he spent four years hopelessly pursuing campus beauty Qin Ruomeng, only to meet the love of his life, Xiao Jinli, after graduation. She had a hereditary heart condition and stopped breathing in his arms at just 28. He spent his entire trillion-yuan fortune developing a life-saving drug, but in the end, he was too late. Reborn as a freshman, he resolutely gave up on the second female lead and pursued the heroine instead, working desperately to earn money so he could develop a new drug. But fate played another cruel trick: the drug failed again, and he watched helplessly as she left him for the second time. Overwhelmed with grief, he pushed the drug through to market, saving countless people, but lived out the rest of his life alone. When he opened his eyes again, it was once more the day he reported for his freshman year. After losing the love of his life twice, his brain forcibly locked away all his memories. He once again began pursuing Qin Ruomeng in a daze. Until one day, a girl named Xiao Jinli stood before him: “Hello, I'm your future wife.” “Did Qin Ruomeng send you?” “…You used to call me your little lucky koi.” She had been reborn too. This time, she would be the one to run toward him.
