I just want to know if it is a happy ending or not. in the book or the show. Someone please spoil it for me 

Novel: it is a happy ending.  Ji Heng (or Xiao Heng in the drama) and Jiang Li is married and have a daughter.  

JH adores his daughter and pretty much listens to her (e.g. when JH is in a bad mood and wants to punish the person, she just have to tell him to stop and he will soften up and do as she wish).
