I have read this bl novel about a year ago. It is a quick transmigration bl,I only remember a bit about its arc. The arc is in ancient china Here the mc is a spoiled brat son of a noble, he is chosen to become the study partner of a sick prince who is in fact ml suffering due to the intake of poison which was meant for the emperor by the enemy nation. So, the emperor really dotes on ml due to his guilt. The mc's father and mother were very reluctant to let mc become the study partner of prince because or. mc is very ignorant and arrogant, which might lead to their family line. In this arc, the mc meets ml in the palace where the noble's sons are gathered around to pick the prince's study partner. The mc gifts sick ml a rattle drum. Guys, Please help me I really want to read it!!!
