A bittersweet feeling

This movie tells us about many things like loneliness . The acting is good specially the person in his 30s playing a playing the role of a 70 year old person.

But the idea of a 70 year old with a high school girl is too much for me.

Also, I felt that some scenes were unnecessary.
Like the one when he was imagining her and thinking about doing something he definitely shouldn't with a 17 year old girl. That was honestly very creepy.

And the romance between her and the assistant also felt somewhat rushed.
