Will there still be tomorrow? Sixteen-year-old Aiko Mizuhara has slowly forgotten what it feels like to be happy. Leaving her trapped between loneliness, anxiety, and a fear of what tomorrow might bring. Then she meets Ren Takahashi, a cheerful and kindhearted boy who believes that even the darkest days are worth facing because tomorrow can always become something better. As their friendship grows, Ren begins to see the pain Aiko hides behind her quiet expression, while Aiko slowly discovers that she doesn't have to face everything alone. Alongside her best friend Mika and Ren's best friend Daishi, their ordinary days become filled with laughter, friendship, tears, and moments they never expected. But both Aiko and Ren carry wounds from the past- fears of being abandoned again. Through every difficult day, they learn an important lesson: tomorrow doesn't have to be something we fear. Sometimes, all we need is someone beside us to give us the courage to look forward to it. And perhaps, when two people find each other at the right moment, even an uncertain tomorrow can become something beautiful. But the question still remains: Will there still be tomorrow?
