SPOILER
Sorry mate, no good ending. Zhishu dies, doctor Ai lives on the rest of his life sad and regretful for not being able to save him. And Scumbag lives knowing Zhishu doesn't want to see him again in the current life nor in the afterlife. He suffers a lot (GOOD) and regrets everything he's done to Zhishu.
Both I suppose. At the end of the story I cried and felt so bad my lungs started to hurt, but I was so thankful because this is what life is. Not always happy, not always it goes the way we want and we can hurt people and be hurt by them. I think it depends on how much you can take. I feel like suggesting you to read, but if you believe you can't take that much stop and maybe you'll re-read it when you are ready(⌒▽⌒)
Sigh.. i read all the replies. It made me so sad reading what the outcome would be, but like at the same time im happy wenxu had to live with that for the rest of his life and that zhishu's pain can just stop once and for all. It's just said that he couldnt be happy. I hope atleast he could taste a little bit of happiness knowing that dr ai cared for him. Ugh breaks my heart still that dr ai and zhishu couldnt be together. But yeah, thats life..

Someone please put me out of my misery and tell me theres gonna be a good ending so that i have something to look forward to in life coz rn i just feel like shit seeing zhishu unhappy and i want so bad for him to be with dr ai :""""")
