Almost identical, Reversal Orchestra if you want comedy or Sayonara Maestro if you want family drama.

1) the mc here goes back to time and is trying to prevent the accident of his dad ( same kind of thrill)
2) smart mc+ good chemistry
3) school romance
4) group of friends

Both have younger guy and older guy relation ship. Boss and emplye relationship. In both younger man try to prove yourself to the world.

both crime mystery thriller fantasy with comedy elements. its about a man and woman sharing same emotions. Gye Hoon is a chef whose twin sister went missing.

The countryside plot is similar, BUT the story is much more coherent, realistic and funnier in TMIISY.
*ML is a rich, spoiled, urban guy in both.
* FL is a down-to-earth rural girl.

But, for me, TMIISY is such a better series (and story) !!
- viewers can learn a lot on organic culture and environnement protection.
- characters are coherent and smart
- Less melodrama and violence (in TRA, too many slaps, tears, stupid tricks).

=> If you haven't yet, go watch "To me, it's simply you"...

Both FL is a coroner in ancient China. Intelligent in uncovering cause of death. Both FL become instrumental in helping ML solve cases. Both ML have a magistrate type of post. Both ML are intelliegent, well respected and feared by many

Face-swapped female lead. And male lead drawn to and falling for the same person twice. Conspiracies and mysteries waiting to be uncovered.

Similarities:
- friends to lovers
- seperation due to misunderstandings

...you will see if you watch the other

Both are Republican Era mini dramas in which the FL is a self aware character in a video game who accidentally gets transferred to another game and must set things back on track.

Both FLs enter a novel in which they are married to the royal ML who hates them and is destined to destroy them. The FLs attempt to escape upcoming events and the novel but in the process the two fall in love.

Both are xianxia mini dramas in which one of the leads is a reincarnation of a god and the other is a demon and both are together in a sect.

Both MLs have a magical object inside their bodies that belongs to the supernatural FL's people, and the FL is supposed to retrieve.

Both couples meet when the ML is still a prince, the FL then is assumed to have died and the ML becomes king, shifting into a harder personality. The two then meet again when the FL returns.

Both are set within the palace and focus on the ML who is the king and the FL who is on a revenge mission against him, with the two sharing a past connection.

Both have the same kind of vibe and both MLs are working undercover with the FL initially accidentally being caught up in the events.
