Just Because! focuses on a group of high school students in their final semester as graduation looms near.
The story centers on several third-year students, each grappling with their own anxieties and unspoken feelings as they prepare for the future.
Their lives are disrupted by the unexpected arrival of Eita Izumi, a transfer student who returns to his hometown after a long absence.
Eita's presence stirs up old memories and long-dormant emotions, adding another layer of complexity to the already emotionally charged atmosphere of their final semester.
The anime explores themes of friendship, love, and the bittersweet transition from adolescence to adulthood as the characters navigate their changing relationships and uncertain futures. It also subtly touches on the importance of preserving memories as seen through the eyes of a second year student keen on reviving the photography club.
