Idk why there are so many negative reviews. It's not an amazing, revolutionary series, but it's watchable and you can have a good time with it, especially considering how short it is. I only started being interested in the plot and characters around ep 3 or 4, as the first few episodes are more from the perspective of a secondary character who kinda functions as a matchmaker but for the viewers' sake. Still, considering the later focus on the romance, I didn't mind too much.
The acting is good, the chemistry feels very natural and the progression of the relationship was sweet and interesting, albeit not without genre-typical drama, especially near the end. The cinematography is nice, especially certain shots with reflections.
There's no problematic content, which usually makes or breaks a drama for me. The female character is sympathetic, even though she functions as an obstacle, we feel for her. There's no dubious consent, even though it's becoming more of a standard nowadays, enthusiastic consent still isn't a given. I especially liked the lack of a clear seme/uke dynamic which I find pointless and, more often than not, demeaning. I'd love to see these actors together in a longer drama, they were the best part of this one and made it watchable.
