Ryu's manga / #Concubine(2)

College Student Empress

Ongoing | Jinyagi | 2019 released

stopped at ch 55. story started well, progressed to stale characters later. emperor is an entitled virgin, and empress is a flat Mary Sue character (she's physically super strong, she's sexually experienced, no trained assassin can get a hit on her -too conveniently OP)

Generation's Queen Ling

Ongoing | Tutu | 2000 released
