After We Broke Up, I Became My Ex-Girlfriend's One True Love

[Pure Love, Angst, Repentance] [Childhood Sweetheart, Parents, Ex-Girlfriend] [Not a wish-fulfillment story. The protagonist suffered enough in the past, so now he gets to live off others a little] As a boy, at the age when first love blossomed, Jiang Huai secretly loved his childhood friend, Jiang Yunyao. But that year, a transfer student joined their class, and for the sake of the newcomer, his childhood friend brushed aside all the kindness Jiang Huai had shown her. In college, Jiang Huai had his first love, Lin Jia. The two were together for seven years, but the moment Lin Jia's ideal man returned from abroad, her love for Jiang Huai vanished like a fleeting illusion. After Jiang Huai was diagnosed with cancer, both his childhood friend and his first love regretted their choices. Jiang Huai became the one they longed for instead. From childhood onward, no one had ever chosen Jiang Huai wholeheartedly. His parents had never given him any warmth, always favoring his younger brother in everything. Jiang Huai swore that if he ever got another chance, he would never let anyone become his weakness again. Later, Jiang Huai met Liu Ruyan, but the disparity in their status meant they were never destined to be together. It wasn't until he met her that Jiang Huai decided he couldn't let her slip away. But the shadows of his past relationships still haunted him, and after she died in an accident, he was consumed by regret. Fortunately, fate smiled on him, and he met her again...
