Matsubara Runa

She is the only daughter of Seadream, a cosy restaurant on the Yume-no-Ura coastline.

Her parents divorced when she was young. She is a brave young girl who runs the restaurant with her mother. While helping out at the restaurant, she is a second-year student at a private school for girls.

She is a pure, innocent, and lovely heroine. Of course, she is a virgin. Tetsuya confesses his feelings for her, but she is unable to take the final step. She is timid about love. There is a thought that has been closed up in the back of her mind until now.
