Secret (2020)

They have the same feeling for me. It's slice of life, really developing a lot of townspeople characters. A main through line is slowly healing from repeated trauma in the countryside, Both also deal with hidden pasts.

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

In both dramas the male lead is a fire fighter, and in both dramas there is romance between leads. (:
