Lost in Forgetfulness

Tianhuang, a big river runs through the east and west, dividing Tianhuang into the north and south banks. The river has a strange gray color. Being close to it reminds people of their deepest love or forgetfulness. It is called the "river of lovesickness" by the world. Mengchen accidentally came to the river and found that the plants growing by the river seemed to be the legendary "flowers from the other side". He couldn't help but guess that this river was not the rumored "River of Forgetfulness"...
