All beautiful things will eventually come to an End, and sometimes it happens much earlier than you'd like to..

25 21 It's a unique drama about youth which highlights young love while beautifully stating the lives of the 5 protagonists. The protagonists and drama takes you back in time to your youthful days that you cherish the various viewpoints on life in different stages of life. Mostly 25 21 delivers the valuable life lessons like it centers on pursuing one's dreams, mother-daughter relationships, sacrifices, first love, friendship, and family, rather than just romance line it covers every element from love to family relationships.

Yi Jin & Hee do love story is beautiful, realistic and heartbreaking. Throughout their journey we can find one's real love, supportive and care towards our loved ones.

I enjoyed the platonic friendship between Ji-Woong & Seung-won because not every close person can be lovers for me it's more than love called friendship. I like Seung-won character & her personality bold and honest straightforward person.

Bona masterfully portrayed her Ko Yu-rim character it represents many of us in today's generation, like complexities, as an ideal and fresh-faced star fencing player on one side but a struggling 19-year-old on the other side.

And the mother daughter relationship between Hee do and his mother is more realistic. Baek Yi Jin family story would represent the family affection and parental love, brothers relationship beautifully..

And one the best part is they choose the 3 Major World contemporary issues to run their story in these days. And WoW they perfectly dealt with the contemporary issues like the IMF crisis, 9/11 and COVID 19 pandemic how this are effected the real lifes of people in those days.

Screenwriting & Direction & Cinematography departments cast departments :-

Another element that can be appreciated about Twenty-Five Twenty-One is that director Jung Ji-hyun has used nostalgia as props rather than mere timeline elements. The director has also maintained a fast pace for the storytelling, keeping the audience engaged. It requires a team effort from the cast, crew, and writer to create an experience for the audience that can move us from tears to outrage to laughing in minutes.
We deeply value their efforts.
The cinematography is also one of the key highlights of the drama. Many Korean dramas carry outstanding cinematography, but I'm marking this as one of the best aspects of Twenty-Five Twenty-One. Dramas typically use a variety of lighting effects ( Colour grinding) to differentiate between two (or more) story timelines. Interestingly, in this drama, they used the same colour filtration. This helps the story telling ( narration ) to connect the two timeframes of the story displaying that certain feelings and experiences travel from present to past generations of characters.

It’s hard for me to imagine anyone else playing Hee-do and Yi-jin and other 3 main characters but them. The entire cast delivers excellent performances, but Kim Tae-Ri as Hee-Do and Nam Joo-Hyuk as Yi-Jin stand out for their ability to capture how the characters support one another.

Ending :- There is absolutely nothing about this series that I dislike. Especially the ending.. The ending received mixed responses simply because Most of the watchers wanted/expected Yi Jin & Hee do end up together irrespective of the story point, but it was unexpected they gave a realistic ending and in my opinion that is what ultimately makes the ending memorable and satisfying. It reflects our real-life scenarios and characters from everyday life.. Yes, in real life or fantasy ( drama world ) not everyone lovestory and gets a happy ending, How
1) Most people don’t end up with their first love because it depends on the circumstances around them.
2) Not everyone doesn’t choose love over their career.
(be rational)
3) Nothing is predictable, that is what the drama is about so as a kdrama lover we are always ready to adapt new/realistic endings not criticizing them badly.

Finally:-
It's a complete nostalgic ride, I may never encounter a coming-of-age drama like 25 21, It's literally created a deep, unique spot in my Heart. This drama made me cry, laugh, and experience all kinds of emotions and 25 21 - overall a love-friendship-inspirational drama for every viewer irrespective of age. The side characters and friendships were equally important as the lead couple, the humor was wonderful and the time span the backdrop presented the story with an enjoyable contemporary environment.
I recommend this drama to everyone who loves kdramas.

My Favourite Line " Life is precious. Let’s love with no regrets while we’re alive " - Baek Yi Jin ?
