Infinite High School Host Club: Hitachiin Hikaru
Sungyeol as the Little Devil Type
Although he is considered the “leader twin,” he is less mature than Kaoru when it comes to managing his emotions and dealing with others. Because of this Hikaru is childishly over-possessive of each club member. Their selling point in the Host Club is their “Forbidden Brotherly Love” package, which has them acting out various ways of bromance for the entertainment of their female customers. 
Hikaru’s rose colour is light blue. In Japanese culture, blue signifies loyalty. Hikaru is incredibly loyal to Kaoru, even to his own detriment in terms of personal growth. In reality, the blue rose does not exist in nature; but in art signifies attainment of the impossible. The pastel nature of the colour reflects a less intense affect on the character, as in a child or adolescent.
