Lonely Yuri

Seri was first seen when she gave Fusa a wake up kiss. Seri pointed out that the time was past midnight and offered to have Fusa stay the night. Seri stayed up and watched while Fusa slept. The next morning, Fusa left for school and Seri invited her over again after school is over.

Seri confessed her feelings for Fusa but she did not accept. Fusa requested a for bath and Seri suggested bathing together. Seri played while Fusa cleaned the bath. Fusa called Seri's name for the first time and Seri was very happy. Fusa stayed the night again.

The next morning, Seri hugged Fusa before she left for school. Fusa went to Seri's home and Seri assured Fusa that she can find a home with her. Seri wished for Fusa to be with her. Fusa apologized to Seri for using her to cure her loneliness but Seri explained that she knew that Fusa was lonely. Seri accepted Fusa as being special to her.

Fusa spent the night and woke up late. She decided to skip school and Seri went to buy cakes for breakfast. Seri then unveiled a maid outfit that she had ordered by mail order. She had Fusa put it on then took photos of her. Seri complimented Fusa's skill in preparing tea and requested her to cosplay.

Seri shoved her finger in a cake requested Fusa to lick it off. Fusa found herself enjoying it but she caught herself and became embarrassed. Seri was surprised by Fusa's bold behavior and cornered her, confessing her feelings. Seri then caressed Fusa's thigh. They then spent the night.

Seri woke up after Fusa. Seri confessed her loneliness and that she wanted Fusa to be with her. Fusa returned her feelings and Seri begged for her companionship. They took a short nap then Seri woke Fusa up. Seri revealed that she will start attending school and invited Fusa to school.
