The solution to trolley problem, according to this drama, is a trainwreck.
Don't chose between few and many, just pile them up on top of each other and sabotage the wheels too so the trolley falls over too after running over everyone else.
And true to that notion, the final episodes are absolute trash.

Not that the first 3/4 or so were so great, either. It was an extremely slow melodrama, with awfully dumb and naive FL who was not at all sympathetic even tho the story did everything to paint her as such. Truly the slowest story progression I've ever seen. And if only the plot reveals were worth it! But no, it jumped from one lackluster reveal to another, in between constant flashbacks to shit we've already seen and prolonged scenes like FL taking a whole minute to decide to answer a phone call or not EACH AND EVERY TIME.

But the absolute garbage the story turned in the end is second to none.
The morals are very sus too ,"sympathize with rapist if he committed suicide" and "tell on your own family if they broke the law" aren't things I can agree with.

Not even superb acting from almost everyone involved, especially Park Hee Soon and Kim Mu Yeol, could save this one. The camera work, scenery and soundtrack were wasted too (not that the ost is that strong anyway, it had like one memorable melody it kept overusing). Don't let anyone fool you by saying this is a mature drama for mature people, it's trash. It's also not makjang, it's not a thriller, nor is it similar to some other titles MDL recommends below, it's no Misty.
