Kekkon Dekinai Otoko (2006)

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!

-Same premise
-Similar storyline
-Both are equally amazing
-Abe Hiroshi has rocked it
-----------------------------------------------------------------------------------------------------------------------

Both of them are about two older adults that argue and have great chemistry together. Both of them are just genuinely good and are a pleasure to watch.

They are pretty much same, they feel is very similar. While watching this show it remind me of the other. I just want people to enjoy them both. They are both masterpiece, so don't miss out.

Both ...

-have a quirky - weird - not believe in love/marriage lead characters
-have Ryoko Kuninaka as supporting character
-are offbeat but highly introspective romcoms: you laugh and entertained, but in the same time you will learn about something

Both male lead's personalities are similar and the stories are the same premise

Both have a main male protagonist, which is an architect and revolve around his colleagues and troubles at work and his prospects of marriage (or the lack of it) + the surprising amount of women (each has a 3 of them interested in him) surrounding him.

Main protagonists are from different genders, but both are strange people who can't express themself well, while being a bit too blunt (or even considered rude) with others. Both of them make comfort with selling houses (although one of them is also an architect and the other is a seller). Both are found somewhat attractive, yet hard to approach and are considered probably hardly to get married... Yet many people pursue them.
