When Ayumu saw Maika running away from home and having nowhere to go, she couldn't leave her alone, so she persuaded Maika to take her back to her room. Ayumu was secretly hiding Maika in the closet because her father might report her if she was caught, but her father, who suddenly noticed Maika, took advantage of Maika's weakness and played with her body as much as she wanted so that Ayumu would not find out.
