The Time Doyen

It is the early 21st century, and a retrophiliac and ingenious teenage boy once lived in a wealthy family that was always full of money, wealthy and parties--- that is, until the murder of his father. His mother fell into a deep depression, to which she used the rest of the money on solaces and leaving him physically, psychologically, and emotionally neglected. Now, his only choice is to go back in time to escape the troubles of modern life.
