Dark Blue and Moonlight Episode 4

I think this is where the decline begins

The whiplash i get from Hai Qing's emotional responses in this is awful. Also, unless they are using grandpa's passing as a sign of everyone leaving Hai Qing alone at the worst time furthering his spiral into depression, why even put that whole subplot in the story for the first 4 episodes? Unnecessary trauma trigger there at least let grandpa last half the show so we are also heartbroken when he goes, not just stuck here watching awful crying over a human we barely saw.
