I dont think she really went out with guys... Just a made up story, to make Yuuko comes to her, thats it..
Really? You think that Yuuko went ten years without meeting a single one of her best friend's boyfriends. I know I would get suspicions if my best friend never introduced me to his girlfriends.
let's say yukko did meet with one of em once or twice.
however knowing how ai's persona, it wouldn't be surprising for her to have a lot of friends, nd most likely all of those meeting were staged.
Imean she seems really good at acting u know,
she must've been an actress or smthing, I mean being able to hide that sly persona of hers behind happy go lucky persona like that is really impressive u know.
on top of that it's so obvious that ai's really sadistic nd prideful person. so I don't think she would go out with those dudes For Real just to make yukko come at her.
let alone being ai's real boy friend, if they really did exist, I bet those dudes were actually scared of her.
with that being said,
at the end of the day.. ai was like, "fuck it.. fuck my pride! Ive had enough! (kissing yukko passionately)"
it means.. after this long 10 years..,
the winner of the endurance challenge is~~ Yuukkoo!!
