I dunno the only romo Sigma pairings I’m into are Sigma/Phi and Sigma/Akane and Sigma/Akane/Phi

I’m into Sigma/Junpei depending on the context particularly SIGMA AND JUNPEI BEING TRANS SUPPORTS FOR ONE ANOTHER but usually they’re pretty awful for one another due to them y’know, being foils and Sigma being a naive pushover while Junpei is deceitful as hell and knows how and tends to exploit people for his own purposes so they have a lot of working out to do
