So he was a Dhampir. No big deal. Nothing to shout about.
His friends in Ireland didn't seem to think so. Some idolised the Kyuns. Other shunned them. Taboo, they would utter beneath their breaths, fearful of being overheard. Taboo to be associated with the undead. And that was what they referred Vampires or any sort of folk even remotely related to them - undead. Suho loved Ireland, and at the same time hated it. It was with an odd mixture of dysphoria and relief when they finally moved to South Korea, messed around in Canada for a bit, back to South Korea, and finally down to Australia.
The fact that Suho even has sisters (or such a large family in general) is something to marvel at, for the odds of such an occurrence are, in his mother's own words, next to none. In a family of seven children (Hyemi at 12, Minho at 14, the great Suho himself at 16, Haneul and Kihyun at 17, Mina at 18 and finally Eunwoo at 19), Suho has had his fair share of being pushed around, coddled, and being the object of chaos. In school, he was always faster, stronger, one step ahead of the rest, and he resented it as much as they did.
But Suho was never good at talking feelings. Or at the emotional aspect of things. He hurt more people than he should have and at the age of 11, committed what many would deem the unforgivable - injure his classmate. It had been so easy to simply flip him over to shut him up... Except in Suho's case this flipping over ended up to be nearly pummelling him through the wall. Needless to say, the situation was messy, sticky, and it was all his ruddy fault. He was suspended for a bit while the school attempted to sort things out with his parents, who returned home so coldly disappointed in him for the first time in his life the boy was duly frightened.
It was his sister Hyemi and the twins that broke the cold spell surrounding him and the rest of the family, and for that till this day Suho feels most attached to them. He returned to school more volatile than ever under the warning that should he turn to violence once again the next punishment meted out would be expulsion. Suho attempted to slip back into the normal rhythm of things but no matter what, he knew he had already done what he had been trying to avoid his whole life - brand himself as a dangerous creature. A being that needed to be chained. The classmate that he had wounded? He had transferred out, but not before effectively tearing apart a young Suho's reputation in his wake.
Helpless and frustrated, Suho now only stuck to himself and turned to Quidditch for company. It was also during this period when he befriended a bunch of wizards from school where one of them had a Muggle family involved in the mafia. Though Suho never really fully immersed himself in their activities (he was much too clever not to lead himself completely astray) their presence filled up the loneliness in him for a good period of time till he finally put his foot down. He does know they want him to return... But he's sure he's had enough of such shady dealings for a bit. Besides, imagine how ballistic his parents would be if they ever found out.
Even though the incident has faded with the years, he still vividly remembers it with bitterness, and tends to see all potential friends around him as enemies. Till he finds it in him to forgive himself, Suho settles with disobeying professors, messing with his classmates, and swinging his broomstick at those who try to poke fun.
