I Thought I Was the White Moonlight Who Was Destined to Be Sacrificed

This book has been giving me too much trouble, so I'm putting it aside for now and starting the Western fantasy one. Don't worry, I'll definitely finish this one. Nan Xin had a dream that the world he lived in was a novel. In the novel, the male lead and his love interest endured heartbreak and suffering before getting a happy ending. Nan Xin, meanwhile, was the male lead Han Qi's unrequited love. He helped the couple hurt each other, bringing their feelings to a deeper level, then died in a car accident so they could reach their happy ending without any guilt. When he woke up, Nan Xin could think of nothing but, WTF! So what if he was living in a novel? Why should he have to die! He refused to accept it!!! To avoid his death, Nan Xin decided that his first step would be to sabotage his blind date. A pleasant conversation? He refused to believe that a man who was two-timing could have a pleasant chat with him when he showed up with a bird's nest for hair and wearing flip-flops! Han Qi had intended to politely turn down his blind date, but was taken aback when they met. The well-behaved little prince he'd met three years ago must have summoned up a lot of courage to dress himself like a vagrant. Han Qi found himself intrigued. So instead of politely declining, he said he looked forward to seeing him again. From then on, Nan Xin tried even harder to make Han Qi's life difficult. But Han Qi smoothly thwarted every attempt. With one of them unaware and the other pursuing him, the two still ended up engaged. At the engagement banquet, Nan Xin wept silently. He was going to die in a month, and he hadn't even finished writing his will. Sob. Seeing him like that, Han Qi panicked and hurried to comfort his darling, only for Nan Xin to shove him away and accuse him: "You cheating scumbag!" Han Qi: "???" Nan Xin decided to throw caution to the wind and expose Han Qi's true colors to his face. "It was pouring that day, and you didn't come pick me up. Were you having a candlelit dinner with Zhang Xiaojia?!" -- "Darling, I swear on my life, there was a traffic jam that day. I was only five minutes late, then spent three hours looking for you in the rain. When would I have had time for a candlelit dinner?" "You said you'd take me out to sea, but then you went hiking with Zhang Xiaojia instead!" -- "Darling, there was a typhoon the day we were going to go out to sea. You spent three days playing games at the hotel, and I spent three days in the room next door playing support for you. When would I have had time to go hiking?" "It took you so long to give me my engagement ring. You must have given Zhang Xiaojia an even bigger diamond!" -- "Darling, you said you wanted a twenty-carat square-cut diamond. Even with an overnight rush order, it takes ten days to make." -- "Also, I've been meaning to ask: who's Zhang Xiaojia?" Nan Xin: "Huh?" This plot seemed different from the novel... Could he have dreamed about a bootleg version? Theme: Love life and face challenges bravely
