"Hedgehogs are naturally timid, irritable, and easily nervous. When they shrink into a ball with thorns, how do you plan to interact with them?" This summer, we will have a new life lesson to learn. This drama describes the stories of several teenagers from families who have lost their parents or become disabled, from breaking the law to self-reflection, sharing with the audience the power of "practicing oneself", integrating life experiences such as youth, love, and growth. The drama brings together traditional folk customs such as lion dance troupes and local temples. The colorful costumes, facial makeup, and architectural monuments with deep Taiwanese local characteristics correspond to the young people's bloody personalities, telling the poetry of young growth.
