Basic Trope: An abnormal physical trait a character is ashamed of is admired by another character.
Straight: Bob has a pair of wings which causes him to be an outcast. His Love Interest Alice however, thinks that they are beautiful.
Exaggerated: Bob's wings are moth-like, horrible, they smell bad, and everyone thinks they're ugly, except Alice who loves Bob mostly for this trait.
Downplayed: Bob has a strange looking mole on his back that Alice thinks is cute.
The wings in question are bird-like and angelic, adding to his already Bishōnen appearance.
Alternatively, Alice thinks Freaky Is Cool, regardless of what Bob's wings look like.
Everyone likes Bob's wings except Alice. Bob, who is very proud of his wings, is baffled by Alice's poor reaction.
Alternatively, Bob hides his wings because eveyone makes a big fuss over how pretty they are, and is relieved when Alice can see past his feathers to who he is inside.
Alternatively again, Bob considers his wings to be his only attractive feature, and Alice struggles to convince him she finds his human features handsome as well.
Subverted: Everyone is freaked out by Bob's wings and refuses to go near him except for Alice, but it turns out she just needs one of his feathers for a scavenger hunt.
Double Subverted: The scavenger hunt was just an excuse to be near him.
Bob's wings aren't just ugly, but autonomous and go out of their way to annoy people. Alice thinks they're cute.
Alternatively, Bob's wings aren't really ugly but Alice is WAY too into them, to the point that she constantly stares at them and tries to feel them up whenever she gets a chance. Bob is creeped out.
Alice tells Bob the reason people make fun of him isn't because of his wings. It's because he's a big baby about it.
Zig Zagged: People pelt Bob with screams because his wings are so ugly, but it turns out they're actually fangirls wanting autographs. Once they get them it's revealed they're fangirls who like mocking winged freaks, but then it's revealed (again) they're all Tsunderes and Can't Spit It Out.
People don't care about his wings, ugly or not. They're more concerned with whether he's part of the good super people or bad super people.
Bob doesn't care about how others feel about his wings.
Enforced: The authors realize that the fangirls are squeeing over Bob's wings, and so have characters start reacting the same way.
"You'd think a guy with angel wings would get a more positive reaction from crowds"
"What are those lumps on my back? They're cancers, aren't they?" "No, they're... wings..." "Well, that's even worse than tumors." "I don't thinkl so..."
Invoked: Bob wants to get together with Alice, so he feigns being all emotional and angsty about his wings to try and get her to react this way.
Exploited: Bob was considered quite handsome and had the attention of many women. Alice was too shy to talk to him so she went to a Mad Scientist, Jerk Ass Genie, whatever and made a deal to give Bob a freakish trait so that everyone would be too afraid to go near him. Bob is now an outcast and Alice uses the opportunity to get close to him.
Defied: Bob realizes that his newfound wings may make him feel like a freak, so he does things to build his self esteem like pose for Alice's paintings, or do community service taking medical supplies to hard to reach places.
Discussed: "I don't mind the gawkers, hecklers, or pelters, Alice. However, if I have to hear one more crack about hovering over a barn, there's going to be a special on street pizza."
Conversed: "Finally, someone on that show realizes those wings just make him hotter."
Implied: Bob has wings and while not too many people make a fuss about it, it seems Alice is the only one who wants to get near him romantically.
Bob feels alienated by the wings because of the gawking. People don't actually think they're ugly, but a lifetime of cruelty makes him believe they do. Alice has to work through the self loathing just to reach him.
Alternatively, Bob's disfigurements are truly horrifying. Alice is the only one that thinks they're beautiful, causing people to distance themselves from her.
Again, alternatively, Bob finds his unusual features very ugly and would do anything to get rid of them. He is seriously annoyed by Alice who doesn't care about his personal feelings and only likes him because of those features. Bonus points if Alice is an annoying little fangirl, and Bob reminds her of some character from her favorite (badly written) work of fiction.
Alternatively one more time, Bob calls Alice out on her claim, who admits that it was a lie to cheer Bob up/make him ignore his wings. This causes Bob to react even worse to Alice then normal.
But, once Bob gets a good PR image thanks to Alice helping him do community/hero work, his self esteem improves and people respond positively to him.
Alternatively, Bob gets help for dealing with the physical difficulties presented by his wings, not unlike the help reserved for people with disabilities.
Alternatively, this behavior is normal for Alice, for better or worse.
If the physical problems with Bob's wings are addressed, he replies that with magic or hammerspace, he can make them disappear and reappear whenever he wants.
Played For Laughs: Bob has a huge, nasty horn growing out of his face. Alice just so happens to be a Nightmare Fetishist who is turned on by his "massive horn" and they make a cute, if really odd, couple.
Played For Drama: Bob s outcast from society and even contemplates suicide until Alice takes him in and cares for him out of sheer kindness, giving Bob a new lease on life.
