Mellow, mature romance with true character arcs and growth built up in the middle of very realistic feeling characters and settings. I will definitely be rewatching parts again.

Jung Ryeo Won is always amazing and brings a touch of realism to anything she takes on, but Wi Ha Joon was delightful as well in his slightly out of the ordinary role turn and they had really nice chemistry together. People looking for a focus on romance will be disappointed, which I assume is the reason for the lower rating and some of the complaints I've seen, but the story was about their lives and the Hagwon activities/ work politics with the romance as part of it, and it worked great for me. The director likes repeating his supporting cast across shows and I'm not complaining because they're all very talented and it's fun to see them play alternate nice and petty across his shows. The secondary cast all got lovely interiority, which is not always the case for dramas.

The character dynamics, including extremely well written out secondary characters, and artistic shot decisions were lovely and triumphed over the overused soundtrack, which was mostly very annoying and the director needs to get over his obsession with irritating english songs played every climactic moment. However, by the end I could ignore it as the story overcame it. I was sad to see it end.
