I agree that the Romi POV section was a weak point. I felt like it suddenly diminished the tension around what Romi was thinking or doing during those few days, when we really should have stuck with Juri and found out along with her.
Now what I think would be neat would be to see the entire story from the beginning from Romi's POV, after completing Juri's side of it (or even when the existing POV switch happens, to build up even more tension before the climax). Romi is cool and guarded for most of the game, so it would be interesting to see what is going on behind the mask all that time. Extra content maybe? :)
