He will change personalities regularly during the working day from Monday to Friday and the rest days from Saturday to Sunday.

Just when the workday personality Chun thought everything was calm, the off-day personality Chun unexpectedly became connected with Gao Lu.
So Chun wandered around Gao Lu in a state of one body and two souls, and the campus story that happened.
