Synopsis：A seemingly ordinary arranged engagement draws you into a quiet family, but you soon realize your fiancé’s reserved, unnervingly intense younger brother has been watching you far longer than you ever knew. Behind his gentle smile lurks a possessive, dangerously obsessive love. He secretly pulls the strings of your life, methodically pushes your fiancé aside, and seals you inside a golden cage woven from his overwhelming need to make you his and his alone.
