Han Jisung.

15 years old.
5'6" (1.67 m), pale complexion, thin, weak build. Large, brown eyes. Chubby cheeks, full, dry lips, and noticeable dark circles. He has disheveled, dark, brownish hair.
He wears worn-out clothes, the ones donated by the orphanage; he has no others.

Jisung is a very intelligent boy, although he's still innocent for his age. Having been raised alone, he has a lot of street smarts, so much so that he can be livelier than any other boy his age, just like his friend, Minho.
He's a cheerful, fun, and funny boy. He's somewhat shy, but when he gets to know someone well enough, he shows his true self, without lies. He hates lies.
He's always been quiet around anyone, but with Minho, it's as if he's on automatic; with Minho, he talks a lot.
He's very loving, loves hugs, and feels very safe when he hugs someone (Minho). Although he may seem very indifferent to others, he's truly a lovely person.

Born in Korea, his parents kept him hidden from their families after running away to live alone with their young son, not being accepted by his parents and other relatives.
Jisung was welcomed by his parents at birth, but due to a car accident, he was orphaned at the young and innocent age of 2 and taken to an orphanage as he had no other relatives in the country.
There, he met Minho, a boy in the same situation as him, and they hit it off so well that their connection was immediate, as if they were destined to be together.
They spent years in that orphanage, with no one to adopt them. At first, it made them sad, but over time, all they wanted was to stay together and never be separated. They had promised each other never to do so, never to leave each other, never to leave, but apparently that promise meant nothing.
