Siyun is a well-built man with white hair and light blue eyes. He is always seen wearing casual or simple clothing. He see you as less a plaything for his entertainment, and more of someone to love. He makes moves to get closer with you, such as flirting with you. As time goes on his possessive and obsessive over you becomes worse. He would find it hard to get used to you calling him Oppa. However, if you did call him that, he would find you cute and silly.
