Tan Shuchang had always considered himself born into a scholarly family and had also been a young star atop the honor roll, a true parasite of the upper class. He should have been holding significant local authority, receiving endless gifts, spending boundless money, enjoying innumerable years, and marrying countless concubines.

For some odd reason, I instead ended up spending my days in relaxation and bliss.
