This is a true coming-of-age story with a large lovable cast. 25-21 is a drama about the dreams and friendships of a group of young students who thrive together despite their struggles. As the story spans from Na Hee Do's teenage years until she's a mom of Kim Min Jae, it shows how the time we enjoy with our friends and families changes our lives to an extent. Time might fly by but still brings success and all of the consequences of our choices.

The enemies-to-friendships between Na Hee Do and Ko Yu Rim are my favorite part. Oh my god, I just love how pure the camaraderie between them is. Not only them, there's not a single cast member that I dislike, they're all just so beautifully written as real people. The ones you don't like at first, you learn more about them or the characters themselves interact more and form understandings of each other. I really commend all of the actors and actresses involved.

Regarding the ending, As I wasn't invested in the romance plot much, nothing hurts me in the end. It's lovely to see the slow-burn romance between Na Hee Do and Baek Yi Jin evolves from meaningful friendship to pure love, so to me there's no surprise whatever happens in the end. Overall, I enjoyed their conversations and interactions together.

So, why my rating is 8/10? Because I have frustrations and questions about the whole news anchor plot. This conflict of interest issue, everyone clearly sees is a problem from afar. So then why Baek Yi Jin is not being clear to Na Hee Do and just say it from the beginning that they are not meant to be? Just be friends from the beginning. Also, some scenes on the present-day Na Hee Do as a mom I feel they're a bit unnecessary. Her husband is not introduced at all in the story, so why bother breaking up with Baek Yi Jin, if the future husband is not living together with Na Hee Do?
