He loves cold weather and is also highly impatient
Before he was born, Sehun's mother (Jaimie), fell in love with a god. Later on, he was born. From the day he was born, monsters hunted him down. When he was eight, he had a vision saying that he must go south to the Bay Area. He told this to Jaimie and she packed his items and sent him to Camp Jupiter. On the way, he found his Imperial Gold cavalry sword (Blizzard). Many monsters threatened to kill him but they were all defeated. After two months, he arrived at Camp Jupiter. He was claimed by Aquilon there and became the Fifth Cohort's Centurion.
Sehun has blonde hair and brown eyes. He is 1.90 metres and is a kkotminam. About 90 percent of girls he know or seen have a major crush on him. A fifth of the boys believe he is homosexual (though he is the complete opposite)
