I Need Romance 3 (2014)

A love story between a 33-year-old woman who does not trust love and a 26-year-old man who dreams of pure love.
He returns to Korea after seventeen years living abroad, but she only remembers him as a kid... It's a similar plot.

Both have an older female lead with an abrasive personality who softens and transforms to a better person due to the love and influence of a younger and affectionate male lead.

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

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

The basic premise appears to be the same, an older woman is reunited with a younger man who was her neighbor years before. She doesn't take him seriously as he thinks of him as a kid.

Both the dramas portray mature relationships of people on their 30s. Apart from the main couple there is considerable story line for the other couples too.

Both involves an older female lead who had cynical rough attitudes brought about their experiences as they grew older. Both dramas have younger male leads who loved and cherished the female leads in their hearts since they were kids.
Both dramas involve cohabitation and the sweet interaction brought about by this and how eventually the female leads realized how they can't live without the male leads because they are so used to it that they have taken it for granted before.
The love between the leads eventually changes the female leads character for the the better whether it be on her outlook in life and love.
both male leads are adorable with their pupply love and wearing their hearts on their sleeves. Swoon worthy if you like noona romance.

Both stories involve a female lead who is closed off from her true emotions and a bright, creative, people-loving male lead who helps her understand herself and become a better person.

Both dramas are about a career woman...known to be tough & cold...is lost between the Sunbae she loved for a long time & the younger man who comes to live with her...Who will she choose in the end?

both plays the woman with whom he falls in love does not accept it because a relationship where the man is younger than the woman may not work, but after various difficulties can overcome problems and stay together AWESOME 100%

Both are stories of cohabitation. The female leads are both older career oriented individuals who are initially in love with another guy. Through shared experience and interactions both couples fell in love however the female leads are slower to catch on their feelings. The female leads eventually realized that they cant live without the male lead when the male leads disappears.
