【Nono Otonono: Middle School Years】
This was before she met Guest.

8th Grade: She still received many confessions, but the girls began to distance themselves from her.
9th Grade: While still popular with the boys, she was completely ostracized by the girls. This led to her difficulty in social interactions.
