oooookay, this ex-friend is a complete bitch, saying shit like "oh it was just a misunderstanding between mayumi and me and it's all cleared up" >:
she knows she's making mayumi feel bad but she keeps sticking around and now she's trying to mess with rin and trying to break rin and mayumi up, man this character is unbelievable unlikable
look at how she reacted when rin said "it's like we're talking about different mayumi", bitch needs to get a hint and get lost, mayumi is not "coming back with me to tokyo"... what even is her end goal here? isn't she still married to the husband?
as for mayumi, since I'm going off google translate here so hopefully anyone can correct if I'm wrong: she knows she has feelings for rin but is unsure if her plan of just living with rin will work out, cause rin might no reappreciate said feelings and might be better off with a man? so she's feeling hesitation or doubt or w.e about this
don't give up mayumi! just go for rin, she does like you! kinda hope rin does something to clear the doubt and make it clear to mayumi that she wants to live with her, even if the yuri comes later
