To put it in a nutshell, it felt like I was growing up with them. Iโve noticed in other dramas, they only focus on the main couple. In this one, Iโve enjoyed seeing every character in the group being fleshed out and understood on the same level as the main leads. This drama covers multiple topics and Iโve never been so happy at the end of one. Out of Hidden Love, A Little Thing Called First Love, Wait, My Youth and 20th Century Girl, this has got to be my favorite.
