The MC only regressed 5 months backwards and he doesn't remember any small golden key details like which stock to invest in or whatever, so don't expect him to be this near-omniscient OP that has everything go his way. He's also so kind and upright that he won't even think to use underhanded means to get back at the villains.

Speaking of villains, there are too many of them for my liking and they all have the same personality--greedy, incompetent, in the position of power. I understand that the author needs to give them screentime, but there's such a thing as too much. Personally, I had to stop between chapters or skip the dialogues if it's not the main couple talking.

Towards the later half, there were less unnecessary dialogue, but there were still a lot. The real moment when the main couple start their counterattack was around c120. It was ridiculous to think they could've done all that sooner since all evidences were literally there. It's double ridiculous because it seemed the villain easily managed to get the evidence the ML has spent a long time getting. Until the end, there's not much substance to the villains. They're just made to be severely hateful. It's triple ridiculous because the author just closed everything as "every bad person got punished". They made it seem to build up to a moment when we finally get to see a healthy work environment for the company, so it was a real disappointment.

I would've liked this story a lot better if there were more details about the MC and ML being sweet. Best we got is a few chapters of them comforting each other. For instance, there isn't even a date event. The highlight of their relationship is when the ML realizes his feelings and when they start to date. Don't get me wrong, they're still proper romantic, but it's unsatisfactory if you're looking for a novel with a lot of sweet moments.

Personally, I'm not a fan of frustrating novels. But if I were to be honest, it did do a good job at being frustrating. It's sad that this is a real portrayal of the Korean corporate life, though severely exaggerated. (Obv it's not just KR that has this work culture). I couldn't help but think how much more miserable the story would have been if our MC didn't have his executive director ML. Still, it was fun to see the villains fall.

The ML is also a very interesting character. He appears blunt and strong, but he's the most broken of them all.
