"Our Secret" is one of the lighter coming-of-age teen dramas that I have watched. It is very romance-focused and doesn't tackle serious issues, and even the pressure of school/studies isn't that bad. The romance is very slow-burn and is nicely paced and done. You can say the relationship has a pretty "realistic" development. The leads do have some pretty sweet moments.

Personally, I don't like FL's character. I don't like loud female leads nor super shy ones either. FL here is the shy, quiet and super introverted type. Comparatively, I like the quiet but strong FL in "My Huckleberry Friends" more. I also don't like FL's voice and the way she speaks. On the other hand, ML has a more normal personality (though he's a genius) and not the typical bad boy or cold-outside/warm-inside type.

I think 24 episodes is more than enough, and it could be one or two episodes shorter. Because the drama is very "slice-of-life", personally I find the pacing OK (not great) but also not too slow. I watched this drama on YouTube and it affects my viewing enjoyment because some songs and music were blocked due to copyright issues.
