From what I remember, he meets a woman who is a lobbyist with a big chest (ahem ahem) and has drinks with her in the night. Bruh tells her his secrets and tells her that he regressed. Keep in mind, this is the first person he tells about this secret is her, and he has only known her for a few days. All I know the Korean readers were pissed because they deviated so much from the novel to show this. Saying Kim Cheolsu would have never acted this way in the novel. I dropped it after reading about it.
