It's easy; we just hit it off.
Thanks for sharing this. I think “meant to be” is one of the most common expressions of “緣分” too.
1) It's fate that brought us together. 2) Being in the right place at the right time. 3) What are the odds? Are you stalking me? 4) Wow, i guess someone up there really wants us to see each other today. 5) We just hit it off . It was easy. We didn't have to try.
