Girlie gets a bad case of cold feet and ghosts the guy and that's just the beginning of deeper issues.
Also, this guy has terrible taste in women, let's be honest. Didn't he know what he was getting into the second time around? He had the woman's case history. That made it hard for me to empathize.
Another one of those Japanese movies where they are unable to communicate properly and in due time to prevent all this trauma happening. Is this based on a manga? I got that sense from the mostly muted expressions of the main characters, punctuated here and there by some demonstratively happy laughter for contrast and background.
I hate that Haru is just a plot device for the main love story. I was really sensing and hoping she would be much more significant. Also, her dad was definitely a sicko. Something very shady going on there.
So you got basically plenty of drama tropes - first love, heartbreak, terminal illness, the male lead suddenly finding out all this about a past love, miscommunication and failure to communicate, I'd say impossibility to communicate the way they're carrying on, low self-esteem, healing through love, a lot of philosophizing about love and all that jazz. Only I got so freaking annoyed at that improbable and stupid ending that I just had to downgrade it. As if that would change anything in this woman's psyche. And what does he do? Suggest the most mundane activity. She left him cause she felt bored and unloved.
So what is the point of this movie? What is it teaching us? I must be dense or something cause I'm clearly missing it.
