Yes, Kyan had a messy bedroom that was disgusting. He did fix the situation when he realized his problem. He also fixed his kids' beds. I hope he teaches them how to do it themselves, as well as set a schedule for once a week for the tasks to be done.
That said, a flaw like this doesn't disqualify Kyan as a lover for either Max or Perry. If either of them thinks they need a perfect mate to love, I would see that as disqualifying them. Perfection is a goal, not a requirement. I would hate to have a lover that insists on perfection.
