If you liked "I'm Not a Robot" you might like "My Holo Love" both shows talked about AI, in the first case there's a robot and in the second case there's a hologram, both the shows deal with the loneliness of the ML (I'm Not a Robot) and FL (My Holo Love) , both the protagonists fall in love with the AI (or...I can't say it because it's spoilerish :P), in both shows the AI risked to be stolen.
I really enjoyed these shows so I really recommend them.

Both dramas revolves around a series of homicides where the right culprit hadn't be found yet.
The police was involved in both cases as an element of disturb , in both dramas the older brothers works in the legal department (one is a prosecutor and the other one is a judge) while the younger brothers collaborate/work with the police. The main difference is the supernatural element in He Is Psychometric.

If you liked I Hear Your Voice then you might like Pinocchio, without knowing they were written by the same person I managed to see the similarities in both drama. Other than having the same actor in both drama the ML is orphan and he has to deal with his tragic past to let everyone knows the truth. I really enjoyed both shows but I still prefer I Hear Your Voice.

If you liked Weightlifting Fairy Kim Book-joo you might like Strong Woman Do Bong Soon both the K-drama have strong women as main characters and they show how they deal with
their strength in their every day life.

If you like "To The Beautiful You" you might like "True Beauty" they're both school drama and they both face the bullying problem even if in the first one it's just mentioned. There's more comedy than drama in both of them and I really enjoyed both shows so much. They're dear to me <3.

If you like "What's Wrong With secretary KIM" you might like "A Business Proposal" both casts are perfect for their roles, there's really a nice balance between comedy and drama, I personally enjoyed both so much !
