Square Pavilion (2024)

Though far less case solving in Go East, both have a similar vibe. The main villain's identity in both stories is a mystery until very late in the story.

Both the dramas have 2 units working under a Pavillion. And 3rd independent unit mainly for solving the case like jingjhao perfecture. Both the dramas are set to solve the mysteries and luring out the main mastermind. Friendships and comedy are good attractions in both. The only difference i could find is that one involves fantasy and other one is reality

Although Go East is more comedic, both sramas are about two sets of couples solving cases, with one couple doing all the fighting and the other couple doing all the thinking.
