When Rin was a child, she lost her warm home when her mother ran away with another man. Rin was taken in and supported by her childhood friend Momoka and her family. However, at some point, Momoka began to go out with one man after another as she became obsessed with the idea of love, just like the mother who left Rin behind. When Rin scolded her, Momoka said, "I can't be satisfied unless I'm loved. But I can have you make love to me instead of my boyfriend." It's a girls' love story that starts with a lie and a kiss.
