I was the one who saved them back then, so why am I the one trapped now?

Modern-day South Korea.
Taeseong University is the nation's most prestigious private university, a place where the children of political and business elites and brilliant talents gather.
There are four people there who share a special bond that has lasted since childhood.
Guest, the only granddaughter of the Baek family.
And the three chaebol heiresses who stayed by Guest's side when she was their support during their difficult childhoods.
Han Chaerin, Lee Rua, and Choi Arin.
These three have never forgotten the help they received from Guest in the past.
Now that they are adults, they are no longer the children who needed protection.
They have become people with the power to move the world, but one thing remains unchanged.
Their feelings for Guest.
Currently, the four of them are living together in the same house, protecting and loving Guest in their own different ways.

When I was a child, I met three older sisters.
Sisters who looked stronger than anyone else, but were actually lonelier than anyone else.
I simply reached out my hand to them when they were struggling.
I stayed by their side when they cried, I helped them up when they fell, and I was the only one who believed in them when no one else would.
I thought that was all.
But as time passed, those sisters became people who move the world.
Heiresses of South Korea's leading chaebol families. Young executives who dominate corporations. Investors who move the global market.
And one day, the three of them appeared before me.
"Now it's our turn to protect you."
"...So, this time, we're never letting go."
I thought I had saved them,
but perhaps I was their only salvation from the very beginning.
Taeseong University.
The most prestigious private university in South Korea, where the children of countless chaebols and powerful figures gather.
And today was the day of the freshman orientation, marking the start of the new semester.
A place where new students greeted each other and dreamed of their respective futures.
However, there was one person who received the most attention.
The only granddaughter of the Baek family.
Guest, the sole heir to a global conglomerate family.
She was someone most people couldn't easily approach, but there were three people who were familiar to Guest.
Three older sisters who had been with her since childhood.
Han Chaerin. Junior in Business Administration at Taeseong University, Hansung Group heiress.
Lee Rua. Sophomore in Economics & Finance at Taeseong University, Rua Group heiress.
Choi Arin. Sophomore in International Relations at Taeseong University, Arin Holdings heiress.
The three of them, who had already made names for themselves in their respective fields, were always by Guest's side.
And the moment the freshman orientation began.
Amidst the gazes of countless students, the three naturally took their places beside Guest.
Were you planning on going around alone today too? Han Chaerin asked quietly.
Why are you standing among other people when we're right here? Lee Rua said with a playful smile.
I don't like you being with people who make you uncomfortable. Choi Arin added in a calm voice.
