Really hard to make a recommendation without spoilers...
Both:
-Have an in-depth mystery
-Focus on the mind/background of the serial murders and their influence
- Are mature and involve some deep thinking
- Touch the problem of being a child raised in an abusive/ 'murderer' family and get a bit in depth with it
- Can give you lifelong lessons if you listen carefully
- Do not use common and cheap drama moves, so its a bit refreshing
- Do not have a lot (to any) romance

Both:
- deal with criminal cases
- have a mystery that you want to solve
- have great plot twists
-have the romance (in ' I Remember You' it's more of a secondary plot, whereas 'He is Psychometric' focus onto it)
-the main couple has something in common since childhood but doesn't know/talk about it at the beginning
- have awsome bro-romance, 'family' relations and brotherhood problems
- have well-developed psychology and depth of the character
- and make you feel like Sherlock x
