18 vs. 29 (2005)

They both contain that fluffy and cute romance between the characters. I thought both match each other well.

Both lead couples' jobs are the same in both dramas .. also both dramas have similarities in the plot .. it feels the same..

Exact same plot line, only GBC is centred around both leads and this is about the female lead. Second chances are everything! GBC is the superior drama though.

In both series after an accident the main girl believes she's a high school student.
Also her main interest tries to make her regain her memories.

- Both dramas are about married couples who are going through a divorce.
- Both dramas are about one lead becoming younger version. But in 18 again the ML really transformed to a younger by the fantasy element, but in 18 Vs 29 FL lost all the memories of her adulthood because of an accident and become younger in her mind.
- Both focus on finding lost love and second chance romance.

Same main plot Idea , In both the female lead has amnesia , ending losing the past 10 years of her life , including her husband and how she fill in love with him , and the journey in order to rediscover the lost love .

main couples in both dramas start their love story anew after marriage and the female lead in each is an uneducated simple woman fighting against a sophisticated rival and her own insecurities to win the heart of the gorgeous husband.

Similiarity:
- Both female lead has mentality of teenager due an accident.
- Both female lead has a teenager crush on them.
- The main lead are lovable! (ofc)

Even tho it has different kind of plot, but both are interesting to watch

In both series an accident causes the main actress to lose her memory about some years of her life.

Similar storyline. Female leads lose memory, husband's face challenge of getting their wives to remember & fall in love with them again.
