Smart Main Character(s) recs?

Can anyone recommend me dramas that have highly smart main character(s)? Someone like Han Joon Hwi from Law School.

try:

• Nirvana in Fire
• Liar Game
• Love O2O
• Rich Man Poor Woman
• Stove League
• Wacko At Law
• Kounodori

Pinocchio may be?

I dnf 'd it . Didn't really like the ship or the way the FL was being treated

I think Stranger is pretty good too but not always easy to follow^^"
