Twenty-Twenty entails the story of 3 main university students. We first have Da Hee, who lives with her single mother. Her mother tries her best to lead Da Hee into a better life, but Da Hee has other intentions of finding her own identity and independence amidst it all. Hyun Jin is a composer and musician. He lives by himself and does not have a good relationship with his parents either, but after one abrupt visit from his mother after three years out of contact, she wants to make things right with him again. And lastly, Ha Jun. He comes from a wealthy background and is known as the 'perfect' student at his university. However, things start crashing down for him when he suddenly crosses paths with someone from high school, making him grabbing onto whatever control he has in order for him to not re-live his traumatic past. This drama focuses on the bad relationships that Da Hee and Hyun Jin have with their parents and the journey of self-discovery of the cast as well. It touches on topics, such as bullying, friendships, suicide, uptight parental relationships, and romance as well as the importance of honesty, freedom, and independence.

What enticed me into this drama is the resonation between myself and Da Hee's situation to some extent, which makes this drama somewhat more special to me. This drama tells the story of normal, everyday lives of 20 year-olds which is always refreshing to watch as it's something closer to our lives and also, since I am also 20, I thought it would be interesting to watch to learn something from this, just like their A-teen series.

The relationship that goes on between the two characters is a bit bland, but at the same time slightly cute as well. Maybe it's just how the two characters are as individuals being new into a relationship, but I wouldn't be too critical of it.

I think the selection of the cast was a great fit for a drama like this. The acting was satisfactory in my opinion, but focussing on Wooseok, he did well for his first lead role in a popular drama. Everyone from this drama really has the potential to do future roles and I'm glad they got this opportunity to do so with this drama.

The OST's are out of this world and fit the vibe of the drama

Overall, this story is a bit slow and there are a few things that have been left unsolved; I hope that when it comes to making a second season if there is going to be one, that they will touch upon those parts. It isn't the most original nor creative story ever, more so on the realistic side, but I enjoyed it anyway as a current 20-year-old.
If you're a K-Pop fan and would like to get to know more about Chan and Wooseok, this is a good place to start
