Avg Kdrama Lover

At first, I started watching this because of kim young dae. I usually love his dramas. I won't judge this drama much yet since I'm only on episode 1, but so far, I haven't understood what the story is.
In the first scene, I can see the FL pass out in an interview, and then she meets her future self, who tells her not to take the job, but she refuses to do so and then ends up just as her future self described her. Then they showed how bad her workplace was, the office politics, etc. Then comes her boyfriend. She goes to the police to say that her bf is missing since the day before, then she states some supernatural possibilities like aliens and d deep hole something. She states that she mentioned marriage, and after that, her bf went out and never came back. Then that night, I think her bf visits her place and tells her that they are not in a financial state to get married and will end up broke and struggle to survive their day-to-day lives. Which I thought was true and practical. But they portrayed him as the villain here, even though he was right, and they broke up. Later, it turns out that he was cheating her, and then they go to the crosswalk, kk embarrassing her bf with the stupid song and dance. The ML sees all this and is like Ohhh, this girl is a warrior, ohh cool Till now, I didn't understand where the story is trying to lead us, and I'm confused about what is happening. I'll try to watch a few more episodes and rewrite this review.
