Hatsukoi (2022)

Both flashback between the present day and their high school days eventually closing the gap between the two periods. The main leads in both constantly reminisce about the past. If you don't mind crying as I did for First Love, 20th Century Girl is a good watch but be prepared with extra tissues!

About first loves,

An elementary school teacher named Takano Takayuki who is gradually losing his ability to see tries to hide this fact from his girlfriend Yoko. She eventually discovers the truth and immediately flies home from Mongolia to to comfort him.

Love story about ML who is blind & FL who is deaf but they found love in each other. They support & understanding each other. I really enjoy melodrama romance movie or dramas.

The plot is almost the same you can feel the character better. Here FL and ML fall in love in their teens in school life but later Fl loses her memories
