Music: I'm not gonna pretend to be an expert. The opening song is simply made for the show and is very cute so it left a last impression on me.

Story: It's a remake of the korean drama but personally I like this take better. Is a nice story as far as dramas about going back and changing the past go. The ending is more satisfying though honestly they could've dragged that out longer and I wouldn't have minded. Would've loved to see the drama expand on the female lead's experience back more. Maybe she could've made significant changes of her own. The plot was light-hearted but oddly got my heart racing in anticipation for the next episode and the final confession. The supporting cast all play a part in building on the characters' roles.

Characters: I only talk about the main female and male leads because I feel like they are all that mattered. The leads are more animated in comparison to the Korean Version. The female lead played just the right amoun of tsundere and I definitely felt the gradual romantic connection blossoming before my eyes that felt very organic compared to the usual love at first sight or outrageous quarreling budding romances of today. I personally fell so in love with the female character that I don't think I be able to watch her in any of her other dramas any time soon. The guy does a great job but I did not particular fall for his character the same way I did for her. The chemistry was there definitely there but their relationship is the very awkward/tsundere kind rather than the loveydovey kind.
