I am actually not a big fan of the Jessica Hsuan and Joe Ma partnerships since I found them really boring together, but I really like them together in Tiger Cubs! Neither of them really pursues each other and they just naturally get together since Joe is always there as Jessica tries to get over the death of her fiance. This tumblr post from episode 12 is basically my favorite scene of them (contains spoilers!). Joe has already re-signed with TVB on a per series contract and Jessica is working out her contract with them, so it looks like they're getting ready for the Tiger Cubs sequel!
Here is the order in which I would rank their collaborations:
1. Tiger Cubs
2. The Drive Of Life
3. A Handful Of Love
4. Lady Fan
