I'm his fake girlfriend

People used to say,
when two people with two different social standard, they won't fit with each other. One who has a higher standard doesn't look at people who has a lower standard and that how the world rules.
But when, the higher rank person takes notice of the lower rank person. What could happen?

In a flash, the lower rank girl's life change by just one sentence, "Will you be my fake girlfriend?". How would her life ends?
