Shen Shuo never thought that his stepmother's taciturn, sensitive and considerate daughter would become an inseparable bond in his life. A coincidence of fate reunited the two broken families, and they lived together day and night under the same roof. From the initial alienation and warning, to the unconscious attraction and temptation of each other. They struggle with the boundaries of morality and bear the heavy shackles of their "brother and sister" status. They are afraid of the eyes of the world and even more afraid of hurting their family members who love them deeply.
However, when the repressed emotions can no longer be hidden, when the intersection of eyes can ignite silent sparks, they finally choose to bravely face this love that is not favored by the world. This is a forbidden love that grows between family and love. They must face the wind and rain from the outside world and the suffering in their hearts together, just to protect the purest heartbeat that has long transcended the boundaries between brother and sister.
Intention: secret love
