No ?
Maybe because that's the imagination that some people wants to happen.. the thought that what happen if they can change the past.

This is really a heart breaking, if this in real life.. the person must be struggle from regretting to not telling her feeling to her best friend. That's super sad.. I don't wanna regret and experience things like this, but also difficult to tell what i feel to my bff. She's too precious to me.
