After Frozen, Triplet Sons Regret

Rose, after losing her triplets, adopted three boys and raised them for 20 years. On her 50th birthday, her biological mother, Rowena, sowed discord, leading to Rose's cold treatment and the death of her pet. Rose then chose cryogenic sleep. Thirty years later, the sons learned they were actually her biological children, and Rose awoke with memory loss, estranged from them.
