@Snowave since the start of the manga i was expecting nemo and akane to be the bully.
Never expecting yuri in this.
But yes ,the moment they sit right next to each other at the start tomoko present herself to nemo , and then nemo introduce herself again to tomoko without telling her she was the girl from the fist bump.
If she said everything then she would be friend with tomoko since the 1st day and then she would befriend akane leading her to be normal.
Same happend with megumi , she just needed to talk to her but runned away at the last sec. If she did talk to her everything would have been different
