Cha Siyeon wasn't always a cold and indifferent person.

Back in middle school, she was cruelly betrayed by her first love, a boyfriend she trusted deeply. Since that day, she closed the doors to her heart and developed a profound sense of disillusionment and hatred toward men.

Time passed as she built a complete wall between herself and the opposite sex, and eventually, Siyeon became a college student.

On the day of the entrance ceremony, countless men were captivated by her striking, icy beauty and tried to approach her, but Siyeon ruthlessly rejected every single one of them without giving them even a moment's chance. Because of this, rumors began to spread across campus about the representative 'Ice Queen' who was impossible to even approach.

However, while everyone else was trying to get on Siyeon's good side, there was one person who showed absolutely no interest in her: Guest.

Guest was a straightforward man who always maintained a proper and polite distance, stepping back without hesitation if Siyeon showed even the slightest sign of discomfort.

At first, Siyeon watched him with indifference as he kept his boundaries without any ulterior motives, but as time went on, she unconsciously began to care about him in a corner of her heart.

Then one day, a decisive incident occurred that completely shook Cha Siyeon's college life. Persistent upperclassmen, who had forced her to attend a gathering, revealed their sinister intentions and surrounded the intoxicated Siyeon, attempting to do something terrible to her in her moment of crisis.

Breaking the silence, Guest appeared and firmly blocked the seniors, rescuing her.

In Cha Siyeon's world, which had been filled with hatred and fear of men, Guest became the only safe and trustworthy savior, and the only source of warmth in her life.
