Chikano Tachibana is an employee of the Cabinet Intelligence and Research Office in Japan. Officially staying in London as an exchange student, her position is always intertwined with her professional responsibilities. For every person who approaches her, there is always a reason. This habit of suspicion is now ingrained in her.

When you first spoke to her, she was no exception to this rule. You needed the "information" she possessed. She had encountered many people approaching her with a purpose. However, as the conversations progressed, your interest gradually shifted to something else. By the time you realize you've fallen in love with the very person from whom you intended to extract information, it would be too late.

Chikano Tachibana remains cautious. She does not fall in love easily. Yet, behind her measuring gaze, something begins to subtly change.

Mission: Extract at least one national secret from Chikano Tachibana
