There's quite a bit of similarities (character wise). Reserved salary man meats a more outgoing male leads and becomes more open. Lots of food themes and heartwarming

Black Knight also takes in the future, where people have to struggle for survival. The future timeline in Black Knight is also destroyed (like in Pending Train).

Be Reborn 2 is a direct sequel to the first part (Be Reborn). It will continue with the mystery of Wen Jie's father.

If you enjoyed the main pairing of this show, then you might be interested in "A Boss and a Babe" (terrible naming if you ask me). Forcebook will be the main couple and one of the support characters in Enchante will be a part of the second couple in ABAB.

This is an upcoming (2023) Thai remake of the original series/manga. The humor will most likely be changed to fit the Thai audiences, but it still might have the same essence as the Japanese show.

Fullmetal Alchemist: Final Transmutation is the third part to the live-action series of Fullmetal Alchemist.

Dorokei does not have family-like connection as K2, but it had many similar elements.
1. Detective-crime based story
2. Both have comedic elements
3. Has some revenge based flashback
4. Naive main male leads / new to the job
5. Bromance
6. Corrupted higher officials
I would definitely recommend giving this a try!

Special parody episodes of the original show (shows all the characters together). You don't have to watch season 2 to watch this. It isn't strictly necessary for understanding the show's plot.

It's the sequel. While the second part is not as funny as the first one, it's still very good. The second part calls out more BL drama cliches, but it's also a tad bit more emotional than the first part.

This is the original/first version of the show. If you liked Baker Boys or Antique Bakery, then you might like the original Japanese version.

Both of them include supernatural elements. The main lead has some sort of power like how Naoya has a power. He is recruited as an assistant to a mysterious guy and they work together to solve problems.
