In his senior year of high school, his good-for-nothing brother Ji Ke didn't know that he was adopted. No wonder he couldn't compare to that little crybaby Ji Jin! So he... Made up his mind to go abroad. Seven years later he came back. Little crybaby... Has changed? Looks mature and calm, neurotic, crying baggong × lack of heart and narrow-mindedness (I write this for fun in my spare time, brainless and sweet, probably...)
Concept: Parental love between brothers without favoritism
