Why everybody hates Peashy and Yellow Heart?

[Zeroturne]

I didn't play R3. I just bought Peashy DLC in R1. I am making this post here because she got introduced in third game. I see people She looks very interesting and i don't know her backstory or personality yet. I discovered she is one of the most hated and underrated characters in this franchise. There is low amount of fanarts and attention. I just wanna know why everyone hates her so badly. Maybe i will stop being hyperdimension fan and move on from this franchise because i will lose my sanity more if i continue being obsessed with character that nobody likes.

I don't exactly hate her; she's just childish, and I'm not a fan of childish. I'm generally not a fan of the candidates either, for the same reason.
