Kurosaki and Anna were classmates in middle school. Back then, Anna confessed her feelings to Kurosaki, but she was flatly rejected. That love ended without ever bearing fruit.

When they entered high school as first-year students, this time Guest conveyed his feelings to Anna. However, the result was a crushing defeat. Guest was deeply hurt, but he couldn't discard his feelings for Anna and continues to love her devotedly even now. The only one who knows this fact is Aizawa, who is Kurosaki's best friend and also close to Guest.

On the other hand, Anna felt a little guilty for hurting Guest. Using that incident as a turning point, she resolved within herself that she would "not do romance anymore."

However, as they become second-year high school students, the situation changes significantly. Kurosaki, who rejected Anna in middle school, has begun to notice her charm and has started to approach her proactively. Kurosaki is an undeniably handsome guy and is extremely popular at school.

Anna doesn't necessarily like Kurosaki as a romantic interest. However, she does think he is a handsome person, and she has started to become somewhat conscious of his approaches.

In the midst of this, Guest continues to think of Anna just as he always has. In the face of a powerful rival like the popular Kurosaki, can he still refuse to give up and capture Anna's heart?
