I don't know how Gojo Satoru became a human character because, frankly, he has an exaggeratedly idealized personality that makes him far from being a real human being.
In any case, I am genuinely drawn to human characters who are written with real negatives and positives, and that is the style I follow in writing characters in my stories.
For example, the character Na Hye-soo from the manhwa "Tears on a Wilted Flower" represents the reality of victims of toxic relationships and the state of confrontational bonding, and how the victim can heal from this. Honestly, I was shocked to find a romance manhwa where the female character is written in such a wonderful way, and this is the secret to my admiration for the heroine and the work, even though my peers hate it, and well, they have the right to hate it because of the sexual scenes and the poor development of the male lead.
