These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
During the festival scene, when the CR-5 are pretending to be traveling performers, they do a sort of impromptu-band thing to get the audience's attention, with some of the instruments lent to them by audience members. What does Ivan get? A triangle.
Squick: Some of Giulio's interests, and the "obligatory piss scene" with Luchino.
Tear Jerker: The best ending of Ivan's route. He's the last one of the group alive (the rest having died, presumedly of old age), dying alone on his death bed thinking of Gian and wondering if he's waiting for him on the other side.
