I'm actually expecting pretty soon (maybe 2-4 more chapters) for the "lonely girl" to not make a request for a little bit, and for the other one to initially be relieved, then to start worrying that she's not interested, and by that route realize her feelings. Or for the requests to stop being romantic (ish) in nature, and start being things that are just useful, and for her to start worrying the lonely girl isn't actually interested in her through that route. Depends on how long Kashikaze wants to keep things going in the current status quo though, seems like developments have been fast enough already that I'd expect them to keep being so, but they could also stay at this point or level of intimacy for fairly long pretty easily I bet.
