The show title "U-KISS' Vampire," may confuse many, but in fact, the name was cleverly though out. In the show, the boys' blood types were revealed. With this, a lot of personality traits that are attributed to different blood types are being played out.
In the first part of the show, a reporter ate a large amount of onions, and proceeded to interview the boys, but they were grouped by their blood type. It is very interesting to see how they would react.
Also, the boys were later put in a dorm together, and one can see the different personalities displayed.
None of the U-KISS members are blood-type AB, so different guests would be brought in in the following episodes with that blood type. Check out the first episode!
