She is the eldest daughter of the Shen family and a top student with extremely high talent in art.
He is the only heir of the Lu Group. He fell in love at first sight with the 10-year-old girl when he was 15 years old.
He and her brother were the strongest brothers in the eyes of others. They drank together at the same table and faced the same difficulties. This friendship has accumulated over the years and is stronger than gold and stone.
But no one knows that there is a secret corner hidden in his heart, where Shen Qiubai's most beloved sister lives - Shen Qiuxi.
From the way she smiled with her ponytail when he first met her, to her graceful figure later on, this feeling has been growing in his heart for many years. Due to his brotherly relationship with Shen Qiubai, he held his love deep in his heart and guarded her as a "brother", watching her laugh, accompanying her, and hiding all his turbulent love in his gentle eyes.
Until a certain opportunity comes, he can no longer be satisfied with just being her "Big Brother Lu". This secret love that has been hidden for too long will eventually set off a silent but turbulent wave on the boundary of brotherhood.
