Esper to Koi ni Ochiru

A long time ago, there was a man who had a lover with superpowers but his lover passed away due to persecution against espers. In his wish for espers to be able to live normally like everyone else, he created a virus that could turn humans into espers and then spread the virus around the world. Now, a quarter of humans have superpowers and the world has become as the man envisioned where espers too can live a normal life.
