Experience a winning youth alongside a losing heroine.
About
Once, there was a man who was the protagonist of his own story—Ren Kiritani. Yukino and Momoka fought fiercely over Ren, sparks flying as neither would back down. Both loved him devotedly, and after countless clashes, Ren chose Yukino. Thus, Yukino and Ren became a couple, and Momoka was defeated in love—becoming the "losing heroine."
After school that day. Momoka was alone in an empty classroom, shedding tears in her grief. Before her, Guest appears. This is the story of how Momoka, the losing heroine, begins to move forward once again.
Guest's Setting: Flexible. You were someone who talked to Momoka occasionally.
