The only story that I can think of is this one, not sure if you've already read it :P

(Not a glow up but the uke used to be "somehow bullied" by the seme)
Any BL where Uke used to be bullied by the Seme because of his looks or something then few years later Uke gets a glowup and they meet again?
I’m just wondering If there are stories like this owo
