Comment by SuspenseGG on 19 Days - Chapter 456

@SuspenseGG Yes, a lot of the chapters jump around to show them together in the future and it's implied in many chapters that they're together (there's another chapter where future Mo gets drunk and thinks He Tian is just teasing him, but it's implied He Tian has a ring in the box and proposes, which makes Mo break down in tears).

@SuspenseGG Also forgot to mention, He Tian is shown wearing a matching Cartier wedding ring with Guan Shan in an official illustration, and I believe you can see other art from Old Xian with them wearing matching couple rings on a few occassions. :) <3 They are 100% dating.
