Ichika is indeed the one to say “I love you.” Shiine is saddened and doesn’t like this, which we learn from the thought bubbles we see at the end. I took that to mean that Shiine doesn’t believe Ichika would say those words to her if she didn’t have the fever. And we all know Shiine wants to hear them from Ichika.
Shiine is “upset” that Ichika told her while under the delirium from the fever, not while she was “normal.”
Nurse definitely knew what was going on, best matchmaker 10/10

I wouldn't say she was upset, more like disappointed or let down that Ichika said those words and don't remember it after her fever had passed
