Naomi is an ordinary high school student who goes to an international school. One day, she loses her memory for the past 4 years. But gradually she begins to search for her identity, and even when her memory returns, she keeps on looking for her real self, and what she truly loves in life.

Both of these love stories revolve around protagonists going through time in different directions (i.e. one person moving forward, another moving back - resulting in one's first day together being the other's last day). They're both highly emotional stories as a result of this seemingly ill-fated love.

High school love story between a shy FL & ML but FL forgot about ML after a week but he tried his best to remind her again. ML didn't know she was ill & FL keep it a secret from ML. The cute scene is when ML throw a book that FL left in the train. Yamazaki Kento drama/movie as a high school student mostly is a must watch.

Both have a time warp idea. The future boy meeting the past girl and vice versa. Although for the japanese movie there's a more complex idea about the time warp thingy. It shows parallel worlds where some endings here are not the same in the other world there is.

Because of circumstances out of their control, the main leads of both movies find time slipping away from them.

Both are romantic films that involved two people from different timelines. However, 'Tomorrow I Will Date With Yesterday’s You' is different in a way that things happened on each characters' modern time while on 'Moments of Love' their romance occurred on different eras,and their story had antagonists.
