Shiki and Ichijo maintain a close friendship. Partly because of the fact that they are roommates. There is no indication of a romantic relationship. But Ichijo did note that Shiki was rather attached to him. They are very good friends, like where Ichijo shielded the possessed Shiki with intentions of protecting his friends. There was also a time Shiki drinks Ichijou's blood, proving a close relationship, but probably not romantic.
