This nostalgic web-drama follows the lives of two best friends growing up together and going through the first love, first heartbreak, hurtful arguments, kidney transplanting and "cellular memory" that makes one of them adopt the traits of another.

?Although not the most coherent and too relying on the unnecessary "big reveal" in the end, the story is quite lovely to watch. My favorite scene is drinking home-brewed makkolli at school in the middle of the night and escaping security guards together. The biggest mistake is making the cellular memory responsible for the arguments between Joon Hwi and Yoo interrupting his personal development, not to mention that cellular memory is just a myth and you could use it more creatively.

Overall, it's still a good drama about navigating friendship, anger, sorrow, love and grief, and the performance from Se Hoon is worth a watch.
