Remember that he’s a lot younger than the other so he doesn’t have to composure or control the others have. It seems only natural that he’d be fairly persistent with his age and life style he’s got. I think eventually he and Taiga will choose each other, just as Kaoru and Yuka have chooses each other.
For me, I dont see age as an excuse for being completely selfish and kinda an asshole (maybe asshole is too strong of a word idk) but he clearly has a concept of right vs wrong but is still trying to steal Kaoru. I do agree with you though that Taiga and Rin will agree to be with each other, I just think that the love between Yuka and Kaoru is kinda bland/almost platonic, while the relationship between Taiga and Yuka would have been much more interesting. Though I understand that the story is trying to convey that love can be stronger than fate/you choose your own destiny
I get we’re your coming from. I personally think age/experience can greatly effect how people react in emotional situations. Or it could be that Rin has never felt safe or at home and naively believes that being with Kaoru will solve his problems and essentially save him from the lonely tiresome existence he’s had up to now. Which is a though process seen in a lot of inexperience youth. That’s why I’m factoring in age, plus the convo with the doc in early panels.
I agree that Yuka and Kaoru’s relationship seems a little more subdued at the moment but I think that’s impart to the pair holding themselves back form each other for various reasons and I’m hoping as the story progresses they’re dynamic will grow.
I wish Kaoru hadn't become a pair with Yuka so that Taiga and Yuka could be together. and I dont like Rin for many reasons but mainly because he is trying steal Kaoru (=・ω・=)
