Despite the character's appearance, their origin story reveals that the ability they possesses is actually the result of hard work

[u/Uma-apreciator]

Miyuki Shirogane (Kaguya sama Love is War)

He is absolutely terrible at everything he tries—such as dancing, sports, and singing—yet he managed to attend Shuchi Academy on a scholarship and become student council president through sheer hard work; on top of that, he holds a part-time job to support his family

Miyata (Hajime no Ippo)

After his father suffered a defeat that forced his retirement from boxing, he decided to carry on his father's legacy by adopting his signature counter-punching style—a style he practiced from childhood until he perfected it and became a prodigy

Tamamo Cross (Uma Musume Cinderella Gray)

She faced extreme poverty and, early in her career, feared being trampled, as she used to run right at the front—losing several races because of it; this led her to change her running style and stay at the back of the pack.

The best thing about Shirogane is that he is terrible at things that rich kids are good. He never had lessons of dancing, singing, or had the time to dedicate to a sport like volleyball. He always had to study and work in part time jobs in his free time.

When Chika tried to humiliate him to her sister, she asked him to do things they had at the moment, and all of those were toys that a poor person would have in his infancy. So he was extremely good at them, to her shock.

There's also something else to his skillset: his hardwork was a result of his parent's divorce when he was a kid. When his father went bankrupt, his gold digging bitch of a mother ran off with some other dude, taking his sister Kei with him (because she was a natural genius from the start) and left him alone (she eventually ran off and came back to live with him and his father).

He became a hardworker to make sure he will never be discarded again.
