I loved the manga so much & I have been waiting for months for it to get subbed & I finally watched it last night.
Story: 9/10 because it's something we know & love. I love cohabitation dramas/movies. It's different, but I still loved it anyway. I wished it was a drama instead.
Acting: 9/10: I thought the acting was great. I love the lead actress. I thought she was natural in this movie. I haven't seen the lead actor in a lead role & I haven't seen much of his other works. But I thought he great. I think they were great in the second half of the movie.
music 7/10: The music wasn't memorable, but it was cute.
rewatch value: 8.5/10: I would re-watch this because it's so cute & innocent love story. It put a smile on my face.
Overall, I recommend the movie if you have read the manga or if you are new to the plot. I think you should watch this if you are trying to watch a Japanese movie. I think you should watch this if you are also new to Japanese romantic-comedies.
