A passionate fan of Kang Tae-hyuk, who is a second-generation idol, Lee Do-yoon, after hearing the information that her ultimate bias is starting her own company, went through intense training and became Tae-hyuk's secretary at GHT Entertainment.

Do-yoon, who was living a happy fanboy life... I mean, secretary life, perfectly cosplaying as a secretary, one day receives a surprising proposal from Tae-hyuk.

"Hey, you, the secretary, How about becoming an idol..."

If Do-yoon succeeds in his debut, Tae-hyuk promises to grant him one wish. As a former idol trainee, Do-yoon expresses his desire that he has been thinking about for a long time, which is...

"If I debut, please spend one night with me."

Unlike innocent Do-yoon, who is excited about the idea of spending the night with Tae-hyuk at a fan meeting, Tae-hyuk misunderstands her words and tries to ignore his increasingly dirty thoughts... Two people with the same goal but different thoughts, embark on !!
Will this secretary succeed in her debut as an idol?!
