I usually hate love triangles as there is often lots of unnecessary drama, but this series was exceptional in the way of portraying the love triangle as a chance for them to grow and change for the better. Da-on with his pushover people-pleasing personality, learned to love himself first. Tae-Kyung learned what love is, and the importance of friends. And my baby Shiwoon learned to properly express his feelings and communicate with others.

I love the side characters, Lee So-Hee (could be counted as the antagonist) is portrayed as someone who's arrogant yet extremely confident and brave in pursuing her love for Da-on. She made mistakes, but she learned from them and became a better person because of it. Namgung is that one friend we all need, always supportive care-free, yet gives the best advice and helps the most behind the scenes when it comes down to it. And their teacher is seriously such a ray of sunshine, and so supportive of his students too.

Would I say this series was perfect? Not exactly. But it is an amazing story of friends, love, and growth.
