Ido is anxious because this is around the same time when Sejin got raped by the brother (other timeline). He is the one behind his brother's missing, probably to prevent the same thing from happening.

it's a regression story, meaning ML regressed back in time. In the original timeline, he abused MC so bad (because he's an ass) which drove MC in original timeline to depression etc. So there's really only two timelines. One before ML's regression, and the one after, which the main story is following now, where ML is trying to atone for his actions in the og timeline.
Wow Instead of focusing on Jaekyung’s redemption and suffering for his mistakes, this new season throws all the misery onto Doc Dan instead, who has already endured so much. Its so unfair that Dan is the one continuing to struggle while Jaekyung is comparatively better off.
AGREED!!! i expected so much more from this szn ╥﹏╥
