in Both dramas:
**Mystery/romance and even crime dramas
**Very similar MLs (it's main similarity of these dramas). mysterious and very charismatic, dark lonely antihero type ML, whos past is secret/mystery and also trauma for him. He is quite playboy, playing with girls feelings while not feeling himself anything, lying them, not regretting causing pain for girls who love him. He doesn't care much about anything, about material or even not material things, it's very hard to know what happens in his head or heart. It's very hard to make him feel anything, especially love.
**Though he is so closed type guy, from first view some may think he is very flirty and even funny, he is that way with FL too.
**FL is interested, intrigued and attracted by ML, wants to know more about him, support him... he opens up with her more then anyone (but still not so much, especially in "Piece")
**While drama develops, opens secret past of ML, overall his secrets and mysterious personality - is he so dark/guilty or not? is he killer or not?
Overall "Smile has left your eyes" is much (!) better and another level drama, "Piece" has this vibe and good details but isn't executed (or story isn't written enough good) as well... but these similarities is there and ML's really are very similar.
#So after Pieces it will be great to watch this great Kdrama (which has original Japanese version);
#After SHLYE you may enjoy with some similar vibes (but not expect same level drama).

Both dramas involve a family secret and a crime investigation. Both male leads have grown up as orphans and experienced difficult childhoods. They are both seen as weird and off-putting by others and the FL's are the only ones that understand their true personalities. Jung So Min also stars in both dramas!
