Why do we wish for the kind of love and pain anime characters have?

I have watched so many anime.
Each time I come across a character, I tend to put myself in their shoes or opposite to them.
Especially falling in love like that is still one of my dreams.
Especially characters like pain, obito, akaza, and many more.
And it's the same for female characters I think.
