I Hear Your Voice (2013)

Although these dramas have different topics I saw someting similar. I believe you might like it. Just give it a shot...

Older successful woman, and a much younger man...In I Hear Your Voice, ML is still in high school while FL is a lawyer...In the other drama, ML is a subordinate at work, FL is the Boss at work

Both female leads are older than the male lead and have a hard time accepting him as a boyfriend because of his age. The females have other female friends and have high paying jobs. They have attitudes.

Older woman/younger man romance, the woman is a lawyer in both dramas (different type of lawyer, but nonetheless, lawyers,) Very pretty MCs, (IMHO).

A bit different background stories, but both end up as romances. SAHPH is more direct about it, IHYV takes a while to get going.

Both I can hear your voice & Maybe, maybe not have a main character that can hear other people's thoughts

Both are amazing law dramas that you should check out. I Hear Your Voice has a bit of a thriller aspect to it though.
