Er*eeKo

Ko is an ex-boy and a traitor.

Personal life
Just like sebby, ko is biracial. He is half Korean and half German.

Lore
When dilly and sebby first met ko in Overwatch, he pretended to only speak Korean. Because sebby and dilly are lowkey koreaboos, they thought this was interesting. Ko turned out to be a funny boy and naturally, we became friends.

Later, ko revealed that this first interaction introduced him to a "great growth in [himself]". This presumably refers to his embrace of his Korean culture. He would continue to make Korean friends in real life, which led to his disinterest in video games. The friends he made are suspected to be druggies. Ko would later become a druggie himself.

Taking the butterfly effect into account, one could argue that sebby and dilly created the conditions for ko to become a druggie, by giving him the self confidence to make Korean friends, who then introduced ko to drugs.
