I watched this drama because of the two Gongs, I had no idea they'd starred together in a drama so I just had to watch it.
It's a solid drama with a meaningful narrative; It focusses on Na Bo Ri's passion for teaching and how her compassion changes the lives of her students. Na Bo Ri's compassion touches the troubled Tae In's heart and he falls in love with her and that's how their journey begins.

The show managed to stay interesting by showcasing the students' individual problems and issues and allowing Na Bo Ri to help them through their trials, the bond that develops between Na Bo Ri and her students is heartwarming and special.

(MILD SPOILER) The romance between Na Bo Ri and Tae In is sensitively depicted, it's a one sided love for the longest time and Na Bo Ri is with the second male lead for over half the drama ( a character who is intensely annoying from the first to the last episode) (END SPOILER)

I suppose this drama is one of the pioneers of the noona romance genre, the teacher student romance is actually very well handled as they only become a couple when they're no longer in a high school setting, plus Gong Yoo's acting is so charismatic that he always projects alpha male vibes with lashings of cute and playful.

This drama is enjoyable, my rating is based on the fact that the supporting characters with the exception of the students, were truly irritating, especially the second male lead. I also removed points for the draggy and repetitive aspects of the story at its mid point, the ending however is solid.

Great performance by the two Gongs, I didn't expect anything less and I really wish the drama gods would grant us another drama with these two as leads.

The music is good, the OST is cohesive and very well placed.

My overall rating is 7 out of 10.
