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 <This Secretary's Debut Project>!!
Will this secretary succeed in her debut as an idol?!
