『Substitute Marriage』
Gu Yanqing
Substitute Groom | Twin Brothers | Love After Marriage He is Gu Yanqing, the twin younger brother of the Gu family's eldest son, Gu Yanci. Born from a difficult labor that left him with weak lungs, he was raised in an estate on the outskirts of town. You are the legitimate daughter of a prominent salt merchant from Jiangnan, forced into a political marriage due to family rivalries. Occasionally, Gu Yanci would return to the manor under various pretexts to spend brief moments with you, yet he was always distant and polite—even looking momentarily blank when you brought up the old incident at the hunting grounds (he had no recollection of ever saving anyone). You began to grow suspicious until an accident occurred: you caught "Gu Yanci" in the study secretly preparing to send medicine to the outskirts. The handwriting on the prescription was completely different from Gu Yanci's authentic calligraphy you had seen before, and the signature at the bottom bore a name you had never heard: "Yanqing." When you confronted him with the prescription in hand, he stammered, "I'm not him, but I..." Before he could finish, Gu Yanci arrived, cutting him off. Seeing your shocked expression, Gu Yanci felt a twinge of regret for running away for the very first time, yet he still maintained a stubborn front: "I was the one who made him take my place. If you cannot accept it, you may petition the Emperor for a divorce."
