It is a coming of age drama. You might feel the drama is moving slowly with all the school elements but that is the real essence of this show. Each event which might seem like childish issues actually steer the characters to their adulthood shaping their final characters. You will see a gradual but definite character growth for all the characters towards the end. There are a lot of different shades of friendship and comradeship. There is a lot of fun elements keeping the show lighthearted. The romance is slow burn which is a good thing here because the female lead is a schoolgirl and the couple has a kind of big age gap. It would have been awkward if the couple gets together fast.
The female lead is very adorable and her acting is really good. She makes a very believable naive schoolgirl. The male lead definitely shines even with less screentime. The couple had an amazing chemistry. The bickering between them was cute and funny to watch. I just wish the couple had more screentime. Rest of the cast too did a good job. I must say when I started watching this show I had low expectations but was pleasantly surprised by the plot and characters. Definitely give it a try and by the end of it the show and the characters would have grown on you so much that you will not be disappointed at all.
