Both productions not only have Joseph Chang (Chang Hsiao Chuan) as ML, they are also quirky (with similar arthouse vibe to them) and bloody.

- Sunny Suwanmethanont is ML in both movies
- Both movies have a similar bittersweet vibe
- Both productions have unexpected endings

Both productions have a similar premise - Sunny is confused about his feelings towards two women. Dear Dakanda is the one with better writing and acting, so if you watched Stay: The Series, you should go and watch Dear Dakanda asap.

Both productions tell the story of undercover policemen and criminals trying to trick each other and prevail

Both are remakes of Cantonese movie "Infernal Affairs" - City of Damnation is an official remake, and The New World was only inspired by it - the plot doesn't follow the original script

Both movies were directed by Park Hoon Jung - while they don't share many similarities in plot, they have the same vibe

Male leads in both movies enter gangland as undercover cops and befriend their criminal co-workers. Both productions have a similar plot - unfortunately I cannot reveal more without spoiling either of these films. If you liked one of them, you'll likely enjoy the other one too

One of subplots is rather similar - "fake" (grand}sons taking care of their "fake" old (grand)mothers with Alzheimer's

Similar premise - MLs in both productions get transported back in time but ML in Don't Touch me, Your Majesty keeps his male body.

Both shows are similar horror anthology web dramas that sometimes deal with controversial subjects.

Both shows have the same main cast and were made by the same screenwriter-director duo (Fatball and 25) making them look almost like spin-offs or remakes

While the plot for both shows isn't that similar, they use the same way of storytelling where each major event is shown from different POVs that complement each other
