Moving from Eskişehir to Istanbul for family reasons, the Servet Family enters a completely different environment. The twins Kerem and Ece, who are trying to adapt to the environment at the private university where they start, will meet people who are nothing like them, and they will embark on a long journey called youth, where they will be swept away by the searches, mistakes and the excitement of first love, where they will discover themselves while moving step by step towards adulthood in growing pains.
While the twins are being tested with growing pains, their father Harun has to return to his father's house, where he has not set foot for 25 years, and the resentment between father and son will force the whole family with deep reckonings. Their mother Beliz will enter a new period of self-discovery.
When the twins' grandfather Asaf and grandmother Ayla start living under the same roof with their son and grandson after 25 years, they will realise that growing up and maturing takes a lifetime.
