Obstacles to finally meet Who My Heart beats

Lhxz and Zext have the same fate. Their perfect life turns into tragedy. They live in a world full of evil creatures. They just want justice to rise, but it seems like they can't get it without killing a life. Life has many twists and turns. Destiny never grows and just stay like a child playing people's life. "To live is to die, and to die is gain."
Destiny will be the one to make their paths cross, but since Destiny is also evil, they will meet in a nice way(note the sarcasm).
They're afraid to love again for love is a painful game, but since they don't hold their fate,they have no choice but to go with the flow and face the obstacles to finally meet who their heart beats.
