myungsoo, or l as he would like to be called, used to have a happy childhood. he played merrily with his friends and younger sister whom he adored. however, all that changed when his mother fell ill and died. as a result, he was seperated from his dear sister and was adopted a wealthy family who loved him dearly. his life took yet another turn when he watched, with his very own eyes, his beloved adopted family getting killed by a few members of artemis (he was in hiding and so he didn't get murdered as well). It was indeed a traumatising experience for the young man and it took a few weeks to get over it. he felt angry and guilty as well and blamed himself for not protecting them. since then, he vowed to stop artemis so that people would not experience the same thing as he had. so he set up apollo which he became the leader of. if he is not working as the leader of artemis, you could find him taking photographs for a magazine. his personality underwent a change as well. he was no longer the cheerful person who laughed a lot and was now serious guy who hardly smiled. but who knows, you could be the one to open up his heart and make him smile again.
