I just finished the series and I genuinely feel empty. This series makes you feel like you were there with them, watching them grow up throughout the 24 episodes. I also loved the aesthetics and the way they used the camera as a diary. This c-drama shows you the beautiful youth of the group that'll leave you feeling nostalgic.
The story might seem simple as the story doesn't contain such plot twists or love triangles or a lot of dragging yet it gives comfort :). I also love that the series ended so peacefully and nicely. And not to mention the proposal of Lurang that made me cry ? (where can I find Zhang Lurang's?).

I'd recommend this c-drama to people who'd rather like it simple and don't want too much chaos and just cute moments, so if you're not sure if you want to start, please do!!
