⭐engaging storylines
⭐i cried so much + crazy tightness in my chest when someone says goodbye (+in action scenes too, like in the "Voice" series)
⭐with the seasoned cast, acting is stellar
⭐I just never tried rewatching crime dramas ever. for my well-being, XD and this will not be an exception

Season 2 hurts more because of the kids. Or it's probably just my maternal instinct kicking in.
It's more interesting than Season 1 because of what Il Yong is able to do. I think it'll be great to explore that in S3. Hopefully, there's season 3!
