Really? first thing that came to mind is that they were biological brothers, but I guess I can't really prove it since you can call both friends and family "brother"
in chinese, i mean
Hmmm Idk they don't look alike so it didn't cross my mind or did you mean the one he met in the office? Then yeah they are brothers. Bu Fan the love interest is friends with the older brother I think hahahaha....
We'll know later on I guess hahahah
oh wait, yeah yeah nvm. i just got the names mixed up
hehe I can think of so many scenarios that could happen
The brother and Bu Fan are friends
Cheng Feng could have met Bu Fan already when they were kids but he couldn't remember
Hehheheheheh if they had a cute past story then even better
