You're Song Yuan, So Who Am I?

Song Yuan died at the tender age of nineteen. His mother died young, and his father married his maternal aunt. For the first eighteen years of his life, he got everything he wanted under his stepmother's hypocritical facade, until the eve of his betrothal, when one drugged cup of wine turned his world upside down. Song Yuan went from being a bright and honorable young heir of the marquis's household to a dissolute rake. His engagement was annulled, and his reputation ruined. To clear the way for her own son, his stepmother framed him at every turn. Song Yuan was driven to become ruthless, scheming against everyone, only for it all to come to nothing. His younger brother became the heir and found a good match, living a happy life. Song Yuan alone was trapped in a cold game of chess, doomed beyond redemption. Even on the verge of death, all he wanted was to ask his stepmother if she had ever felt even the slightest bit of sincerity toward him.

He had planned to kill his enemy with his own hands, but something seemed off... * After finishing his thesis defense, Zhou Jinye was ready to go wild. The moment he opened his eyes, he found himself lying beside a woman in an old-fashioned room. Neither of them had any clothes on. It looked exactly like a dramatic ancient-style caught-in-the-act scene. Zhou Jinye: Exciting. Realizing he had transmigrated into a book, Zhou Jinye was even more thrilled. He was going to find out whether the marquis's lady could handle trigonometry. * Song Yuan sneaked into the marquis's household, planning to rescue "himself" ahead of time. But that man refused to leave, insisting he wanted to fight his stepmother for three hundred rounds. His eyes lit up, and the more he talked, the more excited he got. Song Yuan: ... · Transmigration in the flesh + soul swap; they'll switch back later. · Amateurish household intrigue + political scheming. A wish-fulfillment story that doesn't require brainpower. · A modern, innocent college student who puts his whole heart into scheming, as the gong x a truly ruthless shou who strikes as soon as he decides to act.
