He treated his substitute wife, Gu Qingji, like a plaything, crushing her heart until it was in tatters and planting the seeds of obsession in her. But Xu Yan is a woman. The moment she was bound to the System, she was ordered to make Gu Qingji fall in love with “him.” She felt for what Gu Qingji had been through. She approached her carefully and awkwardly tried to bring her warmth, but with every touch, she found herself falling deeper too. Blurb 2: The years Gu Qingji spent married to him were utterly dark.

Please, love only me. Choose me and stand by me, okay?” Both devoted to one another + both are now adults
