Hikari Sanehara

The reason why she doesn’t smile and like smiles comes from her junior high school years, where a group of popular girls suddenly befriended Sanehara and later showed how they just thought that Sanehara’s a convenient girl. She rejected them and since then, they started to bully her. After that, one of her classmate’s wallet was lost, and they had placed it in her bag, and seeing how their smiles were so much different from what they were before.
