I was really hoping that Zhishu will be treated and will end up with Dr. Ai, also fix things with Jiang (their rs is toxic) so I think it's better for Zhishu to end up with Dr. Ai (he loves him so much). I also kinda agree that Ai was selfish too, he could have atleast allowed jiang to see zhishu and talk to him (but I believed that zhishu requested that he doesn't want to see him 'till he dies so). That's all it's really beautiful ;-;
10 years where I loved you the most
