Vertically filmed micro drama (I rate these on their own sliding scale). General spoilers only below.
Okay for one watch, especially if a fan of one of the actors. The most interesting thing to me was the plot; it was different and intruiging to have both step-sisters reborn and retaining their memories! The leads are cute together and have some sweet moments, but the chemistry is a little flat and there's barely any physical closeness. The ML did a better job showing affection and some desire with his eyes. The FL felt like she was smiling at a good friend, but didn't quite reach an in-love feeling before the show ended. The show is only 65 minutes long though, so the screenplay did a fairly good job balancing all the plot elements given the time constraints. Ending is a little rushed, but it's complete and happy for the leads.
