Things like this ( a form of polyamory) just require trust, patience and gpod communication! Thats literally all that is needed, lots of poly relationships last long and some have even gotten married irl :) it genuinely is just REALLY reliant on communication and trust + in this situation with them being brothers its easier i suppose

Just my opinion, i didnt like the throuple story, like i dont get it, sora and those two, wouldnt one get jealous of the other or somthg?
