The promise made by childhood sweethearts is the sweetest candy in midsummer, but also the most painful knife.
Fu Wanru's entire youth revolved around a young man named Lu Yu.
He is Xiaoyu's brother who protects her, the person who will never leave her, and the secret love she has hidden throughout her youth.
On the day after the college entrance examination, she clutched her confession letter and waited for him under the old locust tree. What she was waiting for was the news that he was going abroad.
The person who said he would never leave her just disappeared throughout her youth.
Ten years later, Fu Wanru became an independent architect and thought she would never see him again in her life.
But fate made them meet again at the project matching meeting.
The boy from the past became her lover, and the person who said he would never leave her finally came back.
Only this time, she was no longer the little girl who only chased after him.
Reunion after a long break, reunion after a long absence, secret love in both directions, the domineering boss protecting his wife.
Lu Yu spent ten years of forbearance in exchange for a reunion; Fu Wanru spent ten years of waiting for an answer.
The night breeze will confess for me, and I will never leave you again.
Purpose: Love that runs in both directions can cross mountains and seas and heal all regrets
