What if she doesn't want a poly ending.
I mean, she know that her relation will be difficult since they can't suck life force from each other so they had to come up with a solution, either having Fuu in the middle or being an open couple and let each others suck life force from other girls.
Just because they need to suck energy from other girls, that doesn't mean their relationship is open. It would be open if they were dating other girls. Sucking energy is just sucking energy. Humans are just food.
They still had to be very clingy to the others girls in order to suck energy and judgin by Konomi habits, it's not just by hugging and handholding.
That doesn't matter. Konomi made it very clear that until she had sex with Yukiko, she never even thought about sex as a way to express love but merely something she does to suck energy. It's probably the same with Yukiko and all her handholding and hugging with Yuu. Most likely she doesn't feel anything about it because she never thought about Yuu as anything but convenient food. Basically, humans are just food to them, not potential romantic partners.
