A story about a scumbag from a primary school who traveled through time and became a god of learning. In order to avoid being OOC and being treated as a monster, he tried hard to pretend that he was not a scumbag, and finally succeeded in the imperial examination and became the prince's teacher.
Helping the emperor to deal with government affairs while helping the queen to deal with palace fights. I don't want to study, but I'm afraid that I'm not a god of learning, so I study hard and I'm a scumbag.
