Yall better get ready for a bucket of tears because it's a bittersweet movie. It's about two 17 year old people who are going to die, one of them is dying in 6 months while the other one will die in a year. They met each other on the hospital rooftop and then forward Ren started visiting Natsuki in the hospital. He would bring her 5 flowers (gerbas) every day every time he visited her. I'll stop spoiling it here but from then forward you will have a bucket of tears at the end of the movie because it's the fact they both died and left Mayuu on her own. I'm so sad that they didn't confess to each other that they liked each other, but atleast they would get some time in heaven together. I absolutely recommend this movie if you're into sad love stories. I HIGHLY RECOMMEND THIS!!!!!!!!!
