I don't usually watch slice of life coming of age dramas cause they can be too realistic for me and I watch dramas to escape but this one is worth the watch, it's short and sweet with a nice message and heartwarming characters.

The positives: The romance was very freaking cute cause Jang Dong Yoon is so freaking cute. The relationship between the teacher and the girls was so wholesome and heartwarming and the relationships between the girls felt realistic and relatable so I liked them a lot.

The negatives: The mother-daughter relationship was too strained for my liking, I really disliked the mom most of the time. The protagonist changed her mind too many times too quickly till it became annoying, but overall I liked her.

Story - 8.0 - The story is very simple yet poignant, I think we've all been in similar (not quite the same) situations or experimented the same feelings as the girls (and boy) in the drama, which made it very relatable for me in some aspects. But at the same time, it has a very positive, sweet and feel good vibe and the fact that it is based on a true story makes it even sweeter.
BUT! It has its annoying, repetitive and draggy parts though.

Cast - 9.0 - Overall the cast did a good job.
Jang Dong Yoon (ML) is just the cutest EVEEER but most important than that, he is such a good actor, my favorite kind of actors are the ones who emote really well and oh boy! does he know how to emote, I don't need the show to spell it out for me to know what his character is feeling.
Park Se Wan (FL) was good too, as always.
The only weak point for me was Lee Joo Young (Hye Jin), is not that she was awful or anything but she could have been less wooden.

Music - 6.0 - It wasn't the best nor the worst, not memorable enough for me to rate it higher but not necessarily bad.

Rewatch value - 7.0 - Since it's fairly short and a feel good story it's possible I'll rewatch it eventually. Also, the romance scenes are so cute that I'll revisit them fairly often for sure ^^
