This is not a good writing. Overdosing on misery will only backfire in this case. Subjecting a single character to all of the common tropes of sadness will lose the emotional impact and genuine human connection. This is also resulted in making the drama feels infinitely longer, you'll keep wishing they just die already. Yet, that wasn't the worst part about the drama. The entire murder/mystery/investigation element was effortlessly bad. At one point the entire nation was chasing them until they gave up, no one cared and no proper follow up. The drama could've been easily cut in half without affecting the narrative at all.
