Both female leads are blamed for the death of the male lead's girlfriend. But in Secret, the female lead doesn't really killed the girlfriend of the male lead, she just took the responsibility for what her fiancee did. Also, both aggressive male leads.

Both female leads trying to solve the mysteries of their deaths. The antagonist (pre-supposed) are very much alike!!

Our Times is like the Taiwanese adaptation of 'He Was Cool'. Both 'bad guy' leads; both clumsy and innocent female leads. And both male leads have 'pasts'. Both awesome and worth watching!
