After My Adoptive Sister Sent Me to Nande Academy, She Regretted Going Crazy

I was originally the adopted son of the prime minister's legitimate son who was lost. I kept my thoughts deep in my heart and never dared to reveal any of them. But the real legitimate son of the Hou Mansion was found. I was falsely accused of poisoning and murdering my legitimate son. Su Qingning looked at me with disgust, "He is extremely vicious and has no sense of shame. Send him to Wutong Academy to learn the rules." Three years later, my adoptive sister finally remembered me and wanted to take me home. But she didn't know that I was already in the first year of entering the academy and could never go back.
