I was more partial to the main couple, but this is still a nice companion piece to the series it span off from, especially for people who wanted to see more of the second couple. It takes some some time and a lot of suspension of disbelief to see the actors as high school characters, but the characterization of the relationship is well drawn. Since this is a direct prequel there was only going to be one kind of ending, unless it was going to show parts from the series. If there was something that could have been shown a bit more is Dong Hee's relationship with the aunt which is a major reason he took himself out of the equation for as long as he did at the end. I really like the build up to the kiss with Ho Tae refusing to call Dong Hee hyung and how Dong Hee has offered to teach Ho Tae what ever he wanted, which leads to Ho Tae asking Dong Hee to teach him how to kiss leading to Dong Hee thinking caveating the teaching lesson with Ho Tae calling him hyung would stop him, but it only doubles down the tension when Ho Tae asks his hyung to teach him to kiss. Kudos to the writing.
