Remember You (2021)

Both are about brothers
one as a "good" and the other "bad".
they both have nice plot twist
both Thai drama

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 ML are very smart people who help to solve murder cases. Both ML are quiet/stand-off ish at first but then warm up to the FL. Both ML are being chased/threatened by murderers while also trying to find said murderers.

basically, the same story its just set in different countries. 2 brothers separated when they were young. the older brother has been looking for his brother since then.

about two brothers that have been separated. the younger brother is a killer and the older brother is trying to find him to stop him. it`s switched for Tantei eye. the brother that helps the police investigation has memory loss about something in his past. the other brother that's the killer leaves clues to make him remember what he has forgotten.
