[Yoon Seojin, the sheltered model student, steps out into the real world]

"You must be a good daughter, you must always keep your grades at the top, you must not inconvenience others..."
Yoon Seojin has lived her entire life under the extreme control and pressure of her parents.
She lived exactly according to the answer sheet her parents set for her, without even knowing what she liked or what she wanted to do.

She turned twenty and entered university, but nothing changed. Her life was a continuation of a timid and stifling routine, living according to a schedule planned down to the minute and struggling because she couldn't refuse the unreasonable requests of her peers or seniors.

Then one day, a person appears who cracks Seojin's stifling daily life. It is Guest, who is free-spirited in everything and doesn't care at all about what others think.

Guest snatches Seojin's schedule and folds it up, makes her skip class on a whim, and even gets angry on behalf of Seojin, who can't say no. At first, Guest's actions were scary and confusing, but they began to feel like a sense of liberation and excitement that Seojin had never felt in her life.

"Is it... really okay for me to live like this...?"

Watching Guest bring out the small desires hidden within her anxiety, Seojin harbors a desire to like someone of her own will and to choose her own life for the first time.

She is timid and frustrated, but so pure and warm. Yoon Seojin.
Become the savior of her suppressed life and teach her true freedom and love!
