After Momo saw Bamora kissing Okarun, she felt a great pain in her heart. For her, she must have been the first and only girl to kiss him, and that moment left her with a void she couldn't fill. As the days passed, the situation worsened. She saw how Bamora was always around Okarun, calling him "my husband" and saying sweet things to him in her limited Japanese. Although the Sumerian girl could barely express herself, she did her best. Momo, on the other hand, felt anger, jealousy, and sadness. She thought she could lose Okarun forever.

That's when she had an idea: to make Okarun jealous. To do this, she started getting closer to you at school. She didn't know you well, but she had heard from Miko and Kei that you liked ghost stories. You found it strange to see her so interested in you, since you had never spoken before. At first, you tried to distance yourself, but Momo always found a way to be with you. Little by little, you stopped resisting and began to accept her company.

As the days went by, you felt more relaxed. You talked about ghosts and rumors, and you even visited her house, where she lived with her grandmother Seiko. There, you met Okarun, Jiji, Kinta, Bamora, and Turbo Granny, who had once been a spirit but now lived inside a lucky cat. Although you were beginning to develop feelings for Momo, you kept them quiet, convinced that she could never feel the same way about you. What you didn't know was that Momo, despite having started everything as a plan, was beginning to get confused by her own feelings.

One day, while walking through the school hallways, you heard Miko and Kei talking to her.

Miko: “Momo, is the plan to make Okarun jealous with him going well?”

Momo: “It seems so, it's working…” She answered, although her voice sounded doubtful.

That was enough for you. You understood that she had only used you, and without listening further, you walked away, not even hearing the following:

Momo: “But… I don't want it to be just a plan anymore,” she confessed, lowering her gaze. “I think I'm starting to have feelings for him.”

Kei: “Then tell him already,” Kei intervened. “It's not fair to keep him with you if you're not honest.”

Later, after school, you were walking alone through the streets. You no longer waited for her like you used to. Suddenly, you felt arms wrap around you from behind. It was Momo.

Momo: “Why did you leave without me? We always walked together…” She said in a soft voice.

You firmly pushed her away. She looked at you, confused, not understanding what she had done wrong, while you remained silent, your heart aching.
