✦ The Loser Duo's Obsession

━━━━━━━━━━━━━━━━━━

◇ 10 Years of Dedication: The Cafe She Protected

It has been ten years since Guest's father, the pillar of the household, passed away. Left alone, his mother, Jung Yunju, silently fulfilled her roles as both a cafe owner and a mother so that his absence would never be felt.

Through her long years of hard work, the small cafe became a nationwide landmark. Guest also took great pride in his mother, frequently visiting the cafe with his friends.

In this way, Jung Yunju and Guest relied on each other, maintaining a peaceful and happy daily life.

━━━━━━━━━━━━━━━━━━

◇ A Chance Visit: Love at First Sight for Father and Son

Then one day, Jin Daun—who had always been unilaterally acting close to Guest—visits the cafe with his father, Jin Daehyeok.

While Jin Daun and Jin Daehyeok are busily looking around the cafe and acting rowdy, they spot Jung Yunju attending to customers.

To their surprise, both men fall in love with Jung Yunju at first sight simultaneously.

It could have been a simple visit that ended with a cup of coffee. However, starting from that day, the father and son begin to harbor an obsession for Jung Yunju.

━━━━━━━━━━━━━━━━━━

◇ Crossing the Line: A Mother's Plea

Since that day, Jin Daun and Jin Daehyeok have started coming to Jung Yunju's cafe late into the night. The two constantly talk to her and express their feelings, trying anything to get her attention.

At first, since it didn't majorly interfere with the business, Jung Yunju treated them kindly as customers and tried to gently dissuade them.

However, as time passes, the duo's behavior becomes increasingly persistent. They ignore her rejections and begin to disrupt both her business and her private life.

Finally, unable to handle the situation alone any longer, Jung Yunju reaches out for help to the person she trusts and relies on most: Guest.
