I get the impression that people need to read less manga about love. In life, you don't have to love to have sex or even live together. They can be a couple for a while, but after that they each leave their own way. If they were asleep, it does not mean that they are a couple. They are now close to what it was between Akihito and Asami, but in a more normal way, Feilong will come when he needs it, not necessarily needing to fall in love to enjoy sex.
