O Homem Que Não Consegue Casar (2009)

The Korean version is based on the Japanese one.

Kekkon Dekinai Otoko is the original Japanese version of The Man Who Can't Get Married. If you enjoyed one, you will probably enjoy the other!

Both drama are about a man who truly loved himself, didn't think they fit for marriage & also self-centred.

both dramas have genius but cold male leads who fall for women who are their complete opposite through the help of their overly meddlesome family.

While saikou no rikon (aka matrimonial chaos) is Japanese, it has many similarities to The Man Who Can't get married. Similarities lying in the general theme and genre, as well as the overall comedy structure of both. Without a doubt the main actors/characters have almost mirroring personalities with few differences lying in occupation etc.

The protagonist in both dramas is an architect in his 40's who has no future plans of marriage but finds the one woman who will change his perception on life.
