I created these characters, but I have no idea what to do with them. Any story ideas?!!!
a lot of the prose here is really elegant, "made from the same hot wire" manages to articulate an at least kinda unintuitive emotion very concisely and effectively the prose never feels didactic, i feel like i'm getting clear themes from the text without it just explicitly telling me what to think about. painting the Narcissus boy is used to reflect on his lack of identity by metaphor, the girl's forehead-tickling fringe demonstrates how she feels restricted by rigid social norms or whatever. and thats pretty rad (or rather appropriate for what you seem to be doing with these characters)
i feel like the characterization of the Narcissus boy is inconsistent... like at the start he's portrayed as putting on a veneer of beauty to hide inner turmoil or something. and he seems to be a passive person, and to not have real substance. Then later you describe him as assertive and even sure of who he is, owning himself and having strong beliefs and intense, concentrated feelings. unless im missing something. i feel like you could unify some of these aspects into a more cohesive character; genuine desire for change coupled with private self-loathing might make for a spicy combination... or maybe he only becomes assertive under specific circumstances and when confronted with specific ideas he cares deeply about??? etc. . it'd deepen the themes quite a bit methinks
as for story ideas uhh, there's a decent precedent for fiction about 60s counterculture and its failure (Fear and Loathing is the only one ive read, but apparently Pynchon has some neat stuff too - Vineland, Inherent Vice). and that historical context clearly has parallels to these characters' situations. so you can look into that for ideas
i see conflict here between genuine desire for revolution and freedom, and the inner (personal as opposed to systemic) anguish of the characters and the ways Narcissus boy lies to himself, which might be worth exploring.
more generally, i see undertones of an 'intimate, personal story in the context of a wider upheaval and historical narrative' kinda thing. which might be an interesting angle to tell your story from
p.s. you seem to be smarter than me so take anything that comes out of my mouth with a boulder of salt
