This is not an update. It is just a biography of Yunho, Jaejoong and Changmin. Well, I'll drop the hint / hints here, so you can start to guess who is actually the boy from previous chapter mentioned to.

Jung Yunho (Vampire Age: 1?? , Human Age: 19) 

He is the vampire prince, a pure blood. He is very powerful especially in combat and also mind controlling. He has brown obs but will turn into bright red when he is angry or lustful (for and also blood). He was engaged to a beautiful fiance, Kim Jaejoong but lost him during an enemy's attack. He searched for him every where, days and nights, and finally found his long lost fiance. However, his fiance was suffered from amnesia and he vowed to make him remember.

Parants : Jung Kangin and Jung Leetuek ( King and Queen of Crystal Country, both are pure bloods)

Cousins : Jung H****** and Jung/Kim K**** 

Kim Jaejoong (Vampira Age: 1??, Human Age: 17)

A half vampire and half human. He is in a training to become the Vampire Knight. He is good in combat fighting and has the ability to make what's in his mind come true. He has black obs but will turn into velvet when he is angry and lustful (for and blood, when he remembers later). He was engaged to Jung Yunho but was seperated with his family and fiance in one of the attack by the enemy. He was found and raised by the Kim Family, one of the famous Vampire Knight. He suffered from amnesia due to the attack. 

Biological Parants : Kim Siwon aka Lord Siwon ( Prime Minister of Crystal Country, a pure blood)

                                   Kim Heechul aka Lady Heechul ( a human and also a very powerful witch, his main ability is healing. He      was killed in an attack)

Shim Changmin (Vampire Age : 1?? Human Age: 16)

He is a pure blood, best friend of Yunho. He is the only boy in the entire Shim Family. He is also a very powerful vampire. He has brown orbs but will turn into purple if he is angry or lustful for both and blood. His ability is combat fighting and the main is mind controlling. He is currently in relationship with Kim Kibum. Changmin thought that this relationship can last forever, however, we can only plan and decide while God will have a say in this.

                 Shim Jihee aka Lady Shim ( A pure blood, always lonely and longing for another son)
