Hello, I'm at Your Service (2023)

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

Miles Wei in both drama's
both rom com genre
similar normal clumsy warm female lead + smart/cold to others lead trope
lots of sweet and fluffy scenes
bingeable
side character relationships

Both dramas have the same actor and actress paired as the main couple, so if you enjoyed their chemistry in one, you will enjoy it in the other.
