Reborn at Eighteen with My Archrival

Jiang Yao and Yun Ye were sworn enemies who had fought since they were toddlers and were still at it in the nursing home. But at the very end, Jiang Yao was one breath short and kicked the bucket before Yun Ye. When he opened his eyes, Jiang Yao found himself reborn in a high school classroom at eighteen. He turned his head and saw Yun Ye at the next desk, sleeping like a log. Looking at his fresh and juicy nemesis, Jiang Yao gave him a kindly smile, then stomped hard on his foot. Before being reborn, Jiang Yao had always found his nemesis unbearably annoying! They had to argue over meals, trade jabs before bed, and even when he got milk tea, half of it would be stolen... Seeing the piles of hair his nemesis had annoyed out of him, Jiang Yao was heartbroken and even went to seek advice from an expert. The expert gave him three suggestions: Either take Yun Ye out, conquer Yun Ye, or stay away from Yun Ye. After being reborn, feeling his own impressive head of hair, Jiang Yao decisively chose the expert's last suggestion. He packed his schoolbag, stomped on Yun Ye, and ran! Jiang Yao: Childhood friends aren't worth losing my hair over. See you never! After Yun Ye was woken by Jiang Yao stomping on him, he discovered that the whole world had changed. His childhood friend, who had fought with him since they were toddlers and all through their school-uniform days, had started avoiding him! But how could he let his nemesis get what he wanted? So he ran! And Yun Ye chased! The next day, everyone knew that the top student and school genius had actually transferred schools!!! And his school-bully deskmate stayed by his side through thick and thin!!! From then on, whether they were eating, running laps, or going to the bathroom, everyone could see Yun Ye clinging to Jiang Yao. Onlookers: QAQ What is this plot where someone gets back what they lost and treasures them so much they'd hold them in their hands and burn incense to them? He loves him so much!!! Yun Ye & Jiang Yao: ??? A seemingly mild-mannered but actually slow-to-warm, sensitive, old-fashioned love interest VS a seemingly cool guy but actually gentle, possessive male lead [Important!!!] - The male lead won't be reborn until much later. - Anything may change before the story begins, but these two things won't: * Both are sexually inexperienced, happy ending, one-on-one (Jiang is the love interest, Yun is the male lead). * Rebirth takes place on a single timeline, no angsty parallel-universe romance. Theme: Study hard and keep improving
