very similar to this one! both revenge dramas but the revenge is between a married couple and his mistress! very entertaining and not boring at all

I haven’t watched this one yet but they are both revenge dramas, but in remarriage and desires the main lead takes revenge against her ex-husbands mistress.

-both main characters are shy and get involved something crazy
-both shows had this ‘illegal’ business thing going on
-also in general from the start the show reminded me of Extracurricular so I had to lol
