A sleep experiment takes them on a journey to an enchanting dreamland where identity and status dissolve, leaving only the fervor and splendor of youth. Gradually, they let down their guards and get closer. Her warm and strong hands guide him to shake off the mental shackles step by step. Back to the enduring darkness of reality, they become each other's exclusive beacon of light. With blooming love in their hearts, every day thereafter is full of contentment and sweetness.
