Zach is a researcher at the Power Grid Research Institute. When he woke up one morning, he found that the street was empty and the people around him seemed to have disappeared out of thin air. So he looked for survivors while studying the cause of the accident. Hard work paid off, and eventually he met the beautiful girl Joanna and fell in love with her uncontrollably. But with the addition of Api, a man who didn't want to be directed, the relationship between the three changed. Zach finally discovered that it was the power grid research that changed the energy of the sun, and the universe was out of balance. In order to restore everything to its original state, Zach sacrificed himself and blew up the laboratory's power grid system.
But the result was not as he expected. In the midst of it, everyone seemed to be the pawn of fate.
