Overall, good stuff.
Like others have said, the thing with Ririko betraying the whole dorm was some ass logic (the boys were logical but got shut down due to violence threat).
As for being axed or not, once the whole dorm knew of Kyuuta and Ririko's relationship, I really don't think there's much to show, if they were really serious about refraining from flirting, so time skip was inevitable.
