The eldest son of Lin Shen and Su Sanxian. He is clever and perceptive, studying math. He showed his mother a math problem with the answer 520 (meaning I love you in Chinese slang) to prove he loves her the most. He used a playful ah at the end of sentences to sound cuter. He is described as a dignified eldest son who thought of including his father when suggesting family meals together. He is one of the three villain children.
