I changed places and moved to be next to the male protagonist as my deskmate. I got to know the male protagonist and also met the male protagonist's childhood sweetheart, and was ridiculed by them.
The heroine made new friends in a new school. Friends were very nice to her, but some people were talking behind her back to smear her. She was at school.
