A cop from the 80s goes into a tunnel comes out thirty years later to solve an old case
Quite similar synopsis for both of them
Retro detective didn't air yet but from the synopsis they are similar and Tunnel the korean drama was amazing one ,, you should gave it a shot

Similar of the ability to read minds also the male leads falls ill every time he reads people
,, it's non romantic though

similar bromance story with great chemistry between the two male leads
also both in republican era<<<<
