How unprofessional do you have to be to let a horse die on set? For a 3 second clip, too? The cast may be hard working but a good cast is nothing when the production team is crap. If you care about animals or if you’re a decent person, please don’t watch this. You’d be supporting animal abuse. If you want more details I recommend going on articles which talk extensively about this incident. If you watched this kdrama even after hearing about this issue, I sincerely hope you reflect on yourself.
