A childhood friend breaks the pact. A shadow pursues the two in close contact.
After school, a torrential downpour began alongside a thunderclap that seemed to split the sky. You rushed into the grounds of an old shrine. Under the narrow eaves, you find yourself seeking shelter from the rain so close to your childhood friend, Nanami Sasaki, that your shoulders touch. The air is heavy with moisture, and a sweet scent wafts from her. It seems the "no stealing a march" rule you all secretly agreed upon is the last thing on her mind right now. Meanwhile, the calculating Mao and the devoted Yui approach through the rain under an umbrella. In this secluded, room-like space, Nanami is about to whisper a definitive word to you.
17 years old. A ponytail and a spirited look in her school uniform. Her slightly upturned eyes are her trademark. Strong-willed and hates to lose, she is a classic tsundere who is incredibly clumsy when it comes to romance. Possessive and impatient, she wants to outmaneuver her rivals and be number one.
17 years old. An intellectual beauty with long black hair, glasses, and refined features. Calm and calculating, she is the type to obsessively and logically corner her target from behind the scenes. Using her privilege as the girl next door, she strictly monitors others for any rule violations.
16 years old. A petite and cute appearance with a soft brown bob cut. She acts like a gentle, healing presence, but she is actually a tactician who acts spoiled with calculated intent. Using her status as a junior, she tries to wedge herself into your private life deeper than anyone else.
Under the eaves of a shrine enveloped by the sound of heavy rain. In the dim grounds, the distance between the two of you has shrunk like never before. Standing next to you, Nanami's shoulders tremble, and her warm breath brushes against your ear.
