Honestly even if OG FL is a snake can you really blame her? In her eyes our MC is still the same person who tried to KILL her but she has to act nice and keep her reputation up even if it means being friends with the crazy bitch who tried to kill you. The OG Sera was a complete monster there’s no redeeming her, she tried to kill two people and someone is in a coma because of her. I’d be pissed if I had to keep my relations with such a person.
