You are the most precious to me

Since five years ago, Melissa had been suffering from a painful incident due to which all her emotion, feelings were also lost with that incident. She only had a great attachment towards her book which was very precious more than her life, which holds a very precious memory of her life. But One day, a guy in black suit let her precious book fall in the ground and mistakenly stepped on the book. She was really mad and directly slapped in his face twice. What happened if she discovered her new boss was the guy whom she slapped?
