My Remaining Years Are Few, So Let Me Admire Life’s Blossoms with You

[Two Male Leads + Both Pure + Sweet Romance + Mutual Devotion + Everyday Fluff] [Infamously double-standard, sharp-tongued, devoted big bad wolf × sometimes sweet, sometimes high-maintenance, delicate and frail little painter] Gu Qingnan, who grew up in the north, had a pen pal from the south named Qi Xiangbei. They hit it off from the moment they first met. Some time ago, Qi Xiangbei was diagnosed with stomach cancer. Only by chance did Gu Qingnan find out that his little pen pal was a delicate young master with a weak constitution and frequent illnesses. Luckily, the cancer was caught early and could be cured. But perhaps from worrying too much, six months after Qi Xiangbei recovered, Gu Qingnan had a nightmare. In the dream, Qi Xiangbei died of late-stage stomach cancer and lay forever beneath a falling dusk and snow... Qi Xiangbei was glad that his first impulsive decision in life, sending a letter, had earned him a good friend. He was sure the other saw him as his best friend, too. That feeling reached its peak when Gu Qingnan was willing to travel a thousand miles to help him fight his illness! So even when Young Master Qi was holding two marriage certificates stamped with the official seal, he was still completely bewildered. Hadn't he just been looking for a good friend? How had they become close enough to share a household registration?! Someone took the little red booklet from his hands. A voice tinged with amusement came from beside him: “Darling, the law itself says we're the best friends in the world. Happy?” Qi Xiangbei stared blankly. “Bullshit. The law doesn't recognize that.” The shameless guy snuggled closer. “Best friend, curse me again. I like it.” Qi Xiangbei's vision went black. “What best friend?! Get lost!!!!!!”
