Tom Riddle, resurrected from the diary from Harry Potter's second year, comes back with one idea in mind: date Harry Potter in order to get him to kill himself.

Meanwhile, future Harry Potter travels into the past, tired of being immortal and deciding there is only one way out of that conundrum: get himself to kill himself before he ever becomes immortal.

But Tom Riddle eventually catches feelings, and must now fight against the consequences of his own actions, a terrifyingly powerful Harry Potter, and Voldemort himself in order to protect the boy he loves.
