Could be either because the word P'sao in Thai can be used to refer to an older sister, an older relative who's a girl (cousins), or just a woman who's older. However, it's usually used to refer to someone you're closed to. So if she isn't a relative, it could be someone she considers as a relative like how we sometimes refer to our bff as a bro or sis.dansaran said:So could Aom be cousins with the girl that sells the house or just good friends?
Ok, so I just looked up the plot synopsis at Kapook and it's her cousin.
