I can't even begin to describe the sheer amount of squeeing this movie brought on. So many reasons to love it, but the first and most important is the slightly nerdy performance of Kento Yamazaki as the ML. He's adorable with his quirky smile and his head full of unruly hair and his ferocious determination to befriend this girl who can't remember him one week from the next. It's neat that the story isn't necessarily a romance. I mean, I get that he's in love with her, but at the same time, friendship plays a really big role in the story. So the romance is almost easily missed, but that's okay because it's just so stinking ADORABLE. I wish I could just have "One Week Friends" set on repeat and do nothing else for an entire day! Anyway, if you haven't watched it, do! If there's one potential flaw it's that we don't really see a lot of what's being written in the exchange diary. I can live with that!
