I Need Romance Season 2 (2012)

It has the same adult relationship feel to it, but I personally liked the second season more. The chemistry between the main couple is stronger.

this is the second season of this show.

It is the original and, by what people are saying, the better season. It centers around different characters but has the same general plot.

it has the same plot kind of, three women wanting to get married. its really a nice drama and a light one

In both dramas we have women in their 30s with strong friendship bound. "I need romance 2" is more mature then "The woman who still wants to marry" but they give the same friendship vibe and character are quite similar.

They are similar. Whereas, INR2 is about women and AGD is about men

The are very simular. They both have a love triangle, and the male leads hide their love. I honestly see them as the korean/chinese version of eachother. Both have cute romantic moments and high tension, and the theme of falling in love with someone who knows you more than you know yourself.

If you haven't seen the other seasons then I recommend that you should watch it.

Although different cast and stories are unrelated the dramas have a similar vibe.

Two friends who love each other (though in In Time With You, neither is willing to admit it to themselves) and how they try to ignore their feelings and be happy with other people.

Same scriptwriter. You can find, that there is same main actress in both dramas.

Attachment problems in a relationship
Sexual tension
Soft eroticism,
Western style romance
Male character with problems

Both deal about childhood friends that love each other. In both dramas Lee Jin Hook plays the male lead, the pair is 30+, lives next to each other and tries to solve their problems with their feelings and the extra guys/girls of their friend.
Main difference: I need Romance 2 the pair already dated.

Both kdramas deal about childhood friends that love each other. Both deal with a life-changing condition. However "More than Blue" has a much more tragic take on this and is a movie, whereas "I need Romance 2" is dealing with this topic in a more fun and lighter way

Both leads grew up together, are best friends and end up living together. Both couples have feelings for one another. The only big difference is that in I need Romance 2 the couple already dated before.
