In these cases your first reaction is not "what would Jesus do?", but be really fucking upset about it, like how Han-eol is. Too bad Da-ae got swept up in this first initial anger, but it's also good they have been through this once before, so she won't just leave him be like in a real situation it would (most likely) happen.
... did you already memorize some old winning lottery number combination in case you went back in time? If not, stop being a hypocrite. This story is not focusing on that part of time travel.
@Maru_1 quote: "...Although I think changing the date is a good idea, isn't the premise about how to change fate? It is implied that as fate draws the two together, it will also ultimately be their doom. That is why Da-ae and Han-eol are struggling, and recent events are making it more stressful because they understand how fate is almost impossible to break. For your other point about investing in the stock or making money quick, I think this story excels in that it is extremely realistic and slow-paced. It's obvious that the story isn't about how the main characters become the most powerful in the world or become imposing figureheads of society, it's just a story about two people trying to avoid fate. Also, it's kinda obvious that you've been reading a ton of TRK or some Chinese/Korean power fantasy. Please just take in the subtle qualities and beauties of this story before you become obsessed over unrealistic and choppy storylines that give a false sense of reality.
