Both leads "will" end up together after the drama end (in last scene of last ep when ML ask FL to find this person and FL ask ML why this guy and ML telling he has cure for zombie to human transformation cure and (in funny tune) both leads talking about fees for finding this guy😂😂)
1 
2.)ML& FL chemistry??
3.) Ending??
ML loss his memory with FL relationship but FL remember everything with ML.(FL still likes ML although ML loss his memory )
So FL joined the group for protect the ML.
It's totally open interpretation to viewers
Like a ML new memories with FL
Main leads relationship like a partner in lifetime without having marriage and child concept
(both leads wanted to protect eachother)
In the end drama
FL only cares ML life
And vice versa ML cares only FL
For me This drama having good ending
