The adult cast was ok, but I much prefered the acting and chemistry of the high school aged Yoon and Seok. Story was your average "enemies" (more like bicker) to lovers with some lukewarm, not really all that relevant side plots. The directing with the camera switching back and forth to focus on whoever was speaking instead of doing wider shots to show the characters actually interacting wasn't my favorite, but the OST was nice and fit well with the mood and story.
