Film producer Na-eun and director Yeong-tae are facing a big decision: investing in a bold adult film project. However, instead of focusing on the task, the two are too busy blaming each other for the disastrous previous shoot, putting the entire project at risk of being shelved indefinitely.

In the midst of this impasse, Na-eun proposes a daring idea: why doesn’t Yeong-tae take on the male lead himself to truly understand the challenges faced by the actors? Hesitant at first, the young director slowly gets swept up by Na-eun’s confident and skillful guidance.

Alone together on set, what begins as a rehearsal gradually turns into a subtle test of emotion and professional boundaries. The real question is, will this remain just a practice session, or is it the start of something that goes far beyond the script?
