A true simp story could be about a guy who always buys his crush expensive gifts without expecting anything in return. He just does it out of pure adoration.
It could be that their storylines and personalities offer an escape or a form of entertainment that resonates with you. Sometimes, we simp for them because they represent something we wish we had or could be.
A heartwarming true simp story is that of a guy who would write love letters to his crush every week. He poured his heart out in those letters, talking about how she made his days better. Even when she didn't respond much at first, he kept writing. After a while, she started to look forward to his letters and they eventually became friends and then more. He was just so sincere in his feelings and efforts.
