    the best

    I am from Saudi Arabia🇸🇦. I want to write my admiration for this series. It was really wonderful and meaningful. I enjoyed watching it very much. I would like it to win the grand prize because it is truly amazing. Thank you very much for the beautiful crew and the hero, Yim Siwang. It was amazing. I will miss it very much and I want another season 😔 I am happy to watch such a story.

    I am happy to watch such a story, no matter how I describe my happiness, I will not give it justice. I hope the hero wins the daesang Thank you so much, the best drama 👍🏻so perfect and funny and warm thank you again 💜

    No boring episodes

    "Boyhood" is a hidden gem that deserves more recognition. The cast, especially IM SI WAN, delivers exceptional performances, and the story captivates with its consistently engaging plot, effortlessly weaving together moments of joy, pain, and self-discovery. The vintage or retro setting adds to its charm, and the ending authentically portrays the behaviors of boys at that age. Each episode is a compelling chapter in the lives of these boys, filled with humor, drama, and moments of profound insight. Overall, "Boyhood" is a must-watch and earns a spot on any top KDrama recommendation list. This series is a true gem that deserves to be cherished and celebrated..........,

    Emotional rollercoaster

    I'll be forever amazed to see how a coming of age kdrama-comedy can easily turn to be a deep drama from one episode to the other. I think this is a characteristic of the seriality made in Korea to have a fluctuating variation of styles within the same season. Probably Hollywood accustomed us viewers to hiper standardized products which, like apples at the supermarket, must be predictable and always maintain the product boundaries of "what's stated in the labels". I'm wondering if this is one of the reasons why K-series are becoming so popular around the world. Probably yes. Well very enjoyable, ultra violence and revenge story at its finest.

    This is crazy fun :)

    It is super fun,never dull.every single character is well written and I am eager to know more about all of them.

    I don t think you have to be a K Drama fan to watch this , I beleive in puberty we are all silly and awkward wherever we might be,so this story is speaking to all of us :) If you are K Drama fan then I can say that it has similiar vibe to Reply 1988 , and the it gives away the same warmth.

    I am really enjoying it so far, and if anyone is deciding shoud they watch it or no,please give it a try you will not regret it for sure. The whole cast is giving amazing performance ,hopefully they will all get many many rewards :D <3.

    One of the best Kdrama of 2023.

    Everything about this drama is top notch. From the acting, to the characters, to the plot. Just everything is brilliantly executed. This was my first time watching Im Siwan in a comic role, and as usual he did not disappoint.

    I'm not someone who writes reviews. I like to be the reader instead, but this drama impressed me so much that I just had to share a few words.

    Not a single episode of this drama was boring. Infact I binged it one go. Something that hadn't done in a long while.

    It just bugged me a little, that there wasn't enough talk about this drama. So I decided to help promote it a little by writing this review. If you're skeptical about trying this drama, then just take my words for it and don't hesitate. You won't regret it.
