O Detetive da Dinastia Ming (2020)

They are Chinese costume drama's that focus around the two male lead characters, who are in a beautiful bromance. Both are based on LGBTQIA+ books, but were censored because of the way China works.

Both are wuxia drama.
Both dramas have 3 MLs who trust each other and has amazing teamwork that helps them to solve cases together.
Bromance at its best in both drama.
conspiracy theories that finally ends with a war.

Another historical drama with Darren Chen as the male lead. Both drams are about investigating and finding the truth.

Both shows are focused on solving mysterious and strange cases in a historical setting. The main leads are male with jobs in the ministry of crime/punishments. There are multiple detective stories all tied up by a larger overarching story which is solved in the finale. There is little to no romance in both shows.

The detectives in both dramas are happy-go-lucky sort of fellows that get serious when a mystery catches their fancy and cannot suffer injustice silently.
TSOMD is a Chinese historical detective series with no romance but is quite similar to SRI&Joy in the sense that the story creates a relaxed atmosphere rampant with mysteries and a subtle undercurrent of court intrigue.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both dramas about the royal court affairs
and detective investigations
Both have Bromance between male leads I think

If you want more bromance dramas in ancient china times, then this is worth checking out.
I love the special relationship between the three different main characters, a powerful eunuch, a low ranked official, and an imperial guard. They are so different but work together so well, worth checking out.

Both have strong chemistry between the two male leads / Bromance

Both are detective based; The sleuth of Ming Dynasty is more investigation and crime solving heavy

Both are adapted from BL novels but without explicit BL

The sleuth of Ming Dynasty is a historical based drama while Guardian is fantasy based
