i currently watching ep 4 , and it's kind of annoying that sabi is always jealous.If someone other than her hers recognition she gets jealous. Hope this behaviour of her changes in upcoming episodes
i really liked the female lead and was hoping to watch the romance between the leads but it's not happening anymore. Replacing the actor would definitely feel weird and introducing a new female lead would cause the writers to rewrite and make changes to the script. Let's see what decision they make.
