If you were given a second chance, what would you do?
Would you use your knowledge of the future to get rich quickly?
Would you become a hero of the century by preventing all future disasters?
Would you use your foresight to build connections and form a harem of a thousand beauties?
Or would you get revenge for future grieves by killing in the past?
Me? What would I do? ... I... would want to be a better senior brother to her.
