对于16岁的女孩Jung-hee来说，一年中最困难的一天是她祖母的阵亡将士纪念日。郑熙通常很难和酗酒的母亲相处，但在这一天，她大喊大叫的祖父的妹妹来了。她每年都会责骂正熙的母亲和叔叔，问她为什么为自杀的祖母做追悼会，而不考虑找到离家出走的祖父。自从他的祖父在正熙出生的那天失踪后，正熙不知怎么地觉得这是她的错。所以Jung-hee决定去冒险，在那里她可以解开所有的秘密，结束她母亲的青春期。
"Can't we all just live together?" It would be nice, but for the twin brothers Il-do and Yi-do, it's just a wishful thought. Born under a cursed fate due to their parents' original sin, one must die for the other to live. To avoid this, they have deliberately cut off contact. However, when Yi-do, who works for a gang, gets stabbed, Il-do somehow hears about it and rushes to donate blood, saving his brother's life. But instead of gratitude, Yi-do attacks him the moment he sees him.
