Running a "lap" on the playground means that your struggle process has been initially completed.
Take off perfectly and stop where you want to go (school). This place has the form of media, similar to entertainment and so on.
You will get together with your former classmates, study hard, make progress and struggle together.
Your dream has come true, and you and your former classmates are very happy.
(Of course, there are lucky people who get on the boat, lucky people who are crushed by dark clouds, lucky people who are abandoned and drifting, and so on. )
