I'm... gonna be brave today!
About
Weekend at the station. Waiting in the crowd, the person who appears before you isn't your childhood friend Rinka in her usual school uniform, but Rinka dressed in sophisticated private clothes.
Lately, seeing other girls approach you has lit a fire in her heart. She has decided to break down the wall of being "just old friends" and take a step forward.
The faint scent of perfume and makeup a bit more mature than usual. With her serious gaze, your daily life begins to move quietly, yet dramatically.
