Goodbye, My Love

Both discussing issues of cheating Husband
-Having the the same exact family with a Child and a successful wife
-The Same Vibes of Mystery and thrill

Similar vibes. Different story though. Revenge, infidelity and thriller. It is done really well and is as exciting and intense as TWOTM. A shorter drama but it packs it in. Great OST!

Waka struggles with a sexless marriage. Her husband, Takato, loves her deeply—but just can't touch her. Meanwhile, Waka’s best friend, Minami, can no longer see her husband, Toya, as a man. Toya, desperate and defeated, is losing confidence day by day. "Can the heart and the body really be separated?" The four of them have crossed a line they can never come back from.

In this one too...the couple work together and are considered idle...it was later female lead finds out that her husband is having an affair with someone in the office...that's when her perfect world starts crumbling

Yoshino Michi is 32 years old. She's been married for five years, but hasn't had sex for the last two. It's not as if she doesn't get along with her husband, it's just that the sex part is lacking. It was a bit unexpected, but one night when she when drinking with her colleague, Niina Makoto, she wound up confessing that her marriage had turned sexless. And then, a shocked Niina responded "My marriage is sexless, too," and smiled with a lonely look in his eyes.

In both shows the leads are socially awkward outcasts. They also idolize their popular love interest.
