BerrySongtteok (딸기송떡)

Rejected by her family and betrayed by her fiancé and scheming half-sister, Efna gets a second chance at life when she wakes up before the accident that was meant to end her. Determined to live quietly as a teacher, she soon discovers that her mischievous Sunshine Class is only the beginning. Add a few politically feuding older brothers into the mix—a dashing captain, an emperor, and an archduke—and chaos is inevitable. Can Efna make it through nap time, or will she lose her sanity first?
