you know, this could easily be resolved.
Like 99% of all manga drama. If they just talked about it :p
Not just in manga unfortunately this also happen in reality..
Exactly! People always complain about how "If they would just talk to each other there would be no drama" in manga and other forms of media, but the stories are like that for a reason! If PEOPLE communicated with each other effectively, there would be fewer bad relationships, a lower divorce rate (because fewer people would get married to the wrong person more often than talking to their spouse would save their relationship, though there's a significant number of those as well), and all kinds of personal drama that wouldn't occur. People generally SUCK at communicating with each other and, surprise, surprise, art imitates life!
As for this one, I don't know that they really need to talk about anything. I think they both get off on seeing each other being hit on by guys, but knowing the guys aren't going to get anywhere with their girl. It's a rush... a turn on... as the title says, a "twisted" fetish of sorts. They're probably quite happy. They guys are totally clueless, mind you...
