In reality, one person is aloof and taciturn, while the other is outgoing and flamboyant; but after falling asleep every night, the two people will exchange their personalities and identities in reality and enter a shared dream.
In the dream, the aloof person acts coquettishly and confesses freely, while the extroverted person is sensitive, inferior and careful.
When she wakes up, only vague fragments of her heartbeat remain. Until a nap at noon, the relationship between the two has undergone earth-shaking changes...
The idea: Two teenagers with gaps in their hearts exchange lives in the same dream and get a glimpse of each other's hidden loneliness. Heal each other across the real distance, understand that the companionship of soul fit can heal all darkness, love and understanding are the antidote to two-way salvation
