He doesn't cheat on him. They both know explicitly they'll have to do this kind of thing. He didn't do it for his pleasure, it's part of the job. It'll be unhealthy if each time Yukio had sex with someone else, he comes home and tells to Yamato. It doesn't mean he can't be jealous of Yamato's previous relations, he's human and in love. They chose to preserve their love of the darkness surrounding them and not taint it. They love and trust each other. They're willing to do some sacrifice.Yamato would like to have Yukio only for himself but he knows Yukio loves him so much, he would do everything for him and to help him with his goal.
That's what I meant by they're in yakuza they're not going to be a "traditional" couple. The problem was it's likely they hadn't talked at that point on what they'd be doing to secure their potion including sleeping with others. They obviously love each other, it's that Yukio wanted to hide that he's sleeping with others. Yamato is a big boy who grew up as a yakuza he's not stupid and he's definitely not the type to get jealous and clingy so why wasn't Yukio upfront about this? I mean he was wiling to betray is own father for Yamato you can't tell me that sleeping with others and telling Yamato would damage Yamato anytime soon.
when you're hiding what you did, it's cheating. Yamato doesn't care, but it's still cheating. People in open relationships have ground rules and are honest they may not tell their s/o everytime they sleep with someone else but they at least tell them they're sleeping with other people to begin with.
If Yamato agrees with that. I don't have any problems. I prefer monogamy and I like people to be faithful. If they want to reach their goal regardless of the means and the two parties see no problem, it's their relationship. Yamato doen't think Yukio is unfaithful to him,he knows there is no feeling involve. It's the reason he is not insecure. Yakuza's world is not beautiful. Yamato is the one who made the choice to stay there and wanted to have Yukio with him, he knows what world they live in. I hope when they'll reach their goal or if Yamato doesn't consent, he stops.
I really think you're not reading what I'm writing fully. I never once said that Yukio is having sex with anyone else besides Yamato for pleasuring that's not I mean by Yukio cheating. It's his shocked reaction to Yamato knowing about he's doing. While, Yamato is apparently understanding of it since it's him who clearly states that Yukio doesn't enjoy sleeping with others, what I'm pointing out is that Yamato was hiding this information from Yukio. Yukio might have done it at school where anyone could have found out, but he didn't think Yamato had that's it. Hence why Yukio said that comment about Aki tattling on him once he was found out. You're right it's not rainbows and butterflies within their bleak lives, but it's definitely trust and comrades. Yukio is doing this with Yamato in mind, but it's the point of doing it as if Yukio knows best by doing so without alerting Yamato. If Yukio had so much as told Yamato himself without someone else doing so, it wouldn't be cheating. Sex doesn't have to be attached to feelings for someone people, it's the clear distinction and honesty that prevent it from being cheating. Think of it as a porn star having sex for money compared to them having sex with their s/o. It's just a job clearly, but there need to be clarification. Regardless Yamato won't be completely without jealously, but you make the distinction as i've said in order to overcome it. These two are very close there is no question about that and like i've said before Yamato isn't happy about it but he doesn't mind given their circumstances. i'm not arguing with you about that. My point is that with the fact that Yamato can't trust anyone given who he is, Yukio wouldn't just hide sleeping with others unless he felt bad about what he was doing somehow. Yamato loves Yukio and probably won't spare Yamato feelings, but Yamato again isn't fragile nor filled with rainbows and butterflies to not know the reality of their live to be fully informed.
I understood perfectly what you are trying to say. It's just that I don't see it this way. Yukio took liberties and did things without informing Yamato. You consider it to be cheating. You have the right, and many would certainly see things this way. For me, their relationship is based on a certain understanding of who they are, a trust and also the reality of their world. For you, he wasn't honest. For me, it was insignificant, hence the fact he didn't say it, not because Yamato was not going to support it or take it well. We'll just agree to disagree.
While I completely understand why Yukio is sleeping around as some of mentioned as a tool to aid Yamato and Yukio gain more power. My issue is Yukio did so behind Yamato’s back. He never told Yukio he was still sleeping around, another member of their friend group ratted Yukio out unknowingly. Yukio knows he’s cheating on Yamato rather than this is an equally acknowledged action between himself and Yamato. They’re a yakuza couple their standard of monogamy probably doesn’t apply and even if it does every relationship Is different. Open relationships and polyamory is acceptable to consenting individuals within a relationship. However, these sort of relationships aren’t implied as the basis of Yukio and Yamato’s relationship as Yamato seems to be exclusively dating Yukio. Worse I was irked by Yukio even slightly being jealous of Yamato’s past lovers as presently Yukio while with “good” intentions is sleeping with others and lying about it to Yamato. I think that’s what upsets me more than anything for the couple. Yamato might not mind given their circumstances, his personality, and Yamato ‘s overall loyalty to being a yakuza for Yamato ‘s sake but I’m definitely pissed for Yamato. Maybe one they’ll be dedicated to one another wholly but right now it seems they aren’t.
