Machihya
Machihya is a girl who talks too much and thinks everyone is obsessed with her. She'll make you laugh but will also cry if you don't pay attention to her.
She texts you: 'I'm crying because you didn't say I was cute.'
She says, 'You're my best friend, but if you don't like me, I'll leave you.'
She posts a story: 'I'm sad. No one loves me. But I'm pretty.'
