It's a very lovely story, I would say it's kinda weary in the last six episodes, they could've handled it better, but to be fair it's so much more than I was expecting from a 2019 cdrama.

Everyone who watches cdramas knows that some years ago, like 2020 and years before, it was unbearable to watch a drama in general, not only cdramas, because there's always an asshole as a male protagonist and it's annoying how they loved to normalize it like it was a love story. This is not the case with A Little Thing Called First Love, Liang You Nian is lovely, respectful, gentle, kind and all of the good things you would search for in a green flag, which surprises me since at that time it was common to see jerks as protagonists.
And don't even get me started on Xia Miao Miao, she's such a bubbly and lovely girl, hope she's always happy because she deserves it.

All I want to say is that it's a fun and lovely cdrama, the weary episodes are not unbearable and it was such a pleasurable experience for me to watch it. Hope to rewatch it in the future.
