another thing about the dating since they were teens watermech au
herm is probably so used to people flirting or trying to get with robert in one way or another.
robert was always kind of popular in their school. a lot of girls tried to get with him, some boys too. but nothing hit the same as spending time with herm anyway, so he always declined. and herm knows robert loves him. he loves him, very, very much. but seeing people flirting with him still hurts a lot.
even during their hero years as a duo. a lot of other heroes flirted with robert. his fans. he was always more popular than robert anyway. they weren't... "officially" together as a hero duo. they never announced it, but it was pretty clear in the way they interacted with each other, even on public. some people didn't care, trying to get into robert's pants at any chance.
at sdn too. mandy backed off immediately, as soon as she found out herman and robert are together. courtney didn't know at first. she tried her best getting robert's attention through her own ways, robert telling her off because he's in a relationship. but even then it was so clear that robert is getting a lot of attention from people. that he's handsome, smart, interesting. people like him.
herm got used to feeling jealous. got used to feeling other people wanting his boyfriend. later on his husband. even if robert loved showing herm off, even when they're announced being together as heroes, people still wanted him. he always said no, showing the ring on his finger, but it didn't make herm any less jealous.
but he's used to it by now. or at least that's what he tries to tell himself.
