Son O Gong

Monkey King
The Monkey King, known as Sun Wukong in Chinese, is a legendary figure. The Monkey King's origins can be traced back to the Song dynasty. He is a monkey born from a stone who acquires supernatural powers through Taoist practices.

He also possesses immense strength; he is able to lift his 13,500 jīn or his 7960 kg staff with ease. He is also extremely fast, able to travel 108,000 li (21,675 kilometres (13,468 mi)) in one somersault. He also knows the 72 Earthly transformations, which allow him to transform into various animals and objects. Son O Gong is a skilled fighter, capable of defeating the best warriors of heaven. He has demonstrated partial weather manipulation abilities, and can freeze living creatures and even gods with his icy breath.

Geumganggo and link to the plot
Son O Gong appears to Oribu during the Chamber of Secrets roleplay. He has been following her prior to the discovery of the first blood writing, since she is a Samjang. This is human who, when eaten, gives the consumer immortality and power. Gong needs to consume her in order to become a deity once again.

((Side note: A Samjang's blood smells like the lotus flower :))

In order to protect her life, Taehyung gives her a geumganggo, a bracelet which makes him dedicated to saving her if she is ever in any danger, as well as making him love her against his will. A week or so later, after he has saved Oribu from big (and not so big) dangers, she becomes annoyed with his constant appearing even when there isn't any initial danger, even following her wherever she goes. He urges her to remove the bracelet (and dragging out the fact that he "loves her" because of the bracelet and if she is unhappy, she should remove it) from him whenever she complains, but she knows that doing so would mean he would kill her. Eventually, she asks Namjoon to freeze the bracelet using his Time Magic, and Son O Gong, without the power of the bracelet over him, admits he loves her. She then proceeds to remove the bracelet in full confidence, trusting he will not hurt her.
