Honestly i can kinda get the gist of how aqua and ruby would be tg cuz it makes sense they whwre fated to be together anyway and i think they already are just not saying anything abt it but it should be ok in my  opinion they should there twins and stuff but its not really a problem at all if they date id love this manga more then ik i should and aqua doesn't mind having ruby being all on him is a huge sign no matter where this manga heads ill still read and enjoy aquaxruby or wherever it heads all the way
