Eight 16-20min episodes. The whole production is very well done and happily satisfying. The only weak link is the music, which was meh. Would highly recommend, though I probably won't re-watch frequently.

Tension is masterfully and evenly sustained as the present unfolds and the past is revealed (university and highschool). There's a lot of jumping back and forth but it was fairly easy to follow, especially once I recognized this visual clue: in flashbacks the boys wear a highschool uniform that has a blue and red pattern on the inside of their collars! If you see that, it's in the past.

The premise kind of felt like a Japanese BL; a fantastical take on something mundane that sets up a romance, almost like it’s fated. The feel of this series remains very Korean though; strong storytelling with great acting, lovely cinematography, and a well-written script with a lot of earnest and sweet moments. There is some angst but also communication (eventually) and a satisfying resolution.

The two leads have great chemistry and their yearning is tangible. Kisses are just pressed lips yet still manage to contain emotions and passion in their gentle sweetness.
