Female Characters like Song Jiwon from Age of Youth?

I resonated so much with Jiwon’s wacky, blunt and carefree—yet still sensitive and introspective, attitude. But I can’t seem to pinpoint any other female leads with a similar personality to hers. Any recommendations on a drama with a similar character? Her relationship with Im Sungmin kind of reminded me kind of the Reply 1997 main couple: a tsundere male lead and an oblivious, wacky FL. So maybe even something along those lines.
