One is from Asia, the other is from America; one is from a poor background, and the other is from a noble background; one is walking in the rain of bullets all day long, and the other is living a life of wine and meat. They met in a big explosion that cost hundreds of lives. Crisis strikes again and again. For the most noble belief in their hearts, they can only work together and never give up. "You will always be my heart. It will beat constantly and stimulate my body. The powerful heartbeat reminds me all the time. No matter what happens or what I say, never give up."
