On Ha-jae, a once-in-a-thousand-year handsome trainee. After rebuffing a sponsor's proposal and kissing his debut goodbye, he vowed to not step foot into the entertainment industry again.

Find your hidden talent and grow into an idol,
Play hard to get with the System that doesn't listen well/be disobedient,
Figure out the past of the transmigrated character/character you've transmigrated to.

Whatever works, however works, as I please.
First, go onwards, make a challenge, and take it head on!
