A tiger's poison cannot eat its seeds, but Ke Yan Huan was pushed into the abyss by his father's own hands.
A school bullying incident made Yan Huan and Yi Xinzhou meet. A car accident made Yi Xinzhou never forget Yan Huan again.
After years of separation, the two reunited. By chance, Yi Xinzhou made Yan Huan realize that there was something hidden about what happened back then.
New clues in the old case, his father's resolute suicide, and an intricate spider web slowly unfolded, and the center of the spider web pointed to the person who had been with Yan Huan for many years, the person who Yan Huan regarded as his second father.
Yan Huan: "Yi Xinzhou, don't be too nice to me."
Yi Xinzhou: "I really follow my old man on this point."
Yan Huan: "What do you mean?"
Yi Xinzhou: "It means, I don't."
