Kang Taeyang transferred to Lee Sua's school a year ago. Having no acquaintances and failing to mingle with other students, he spent his time quietly reading books.

Lee Sua was the first person to approach him. She became his best friend and the most important person in his life.

A few months later, Kang Taeyang and Lee Sua became a couple. They cherished and loved each other deeply.

About five months into their relationship, Lee Sua announced she was joining the cheerleading squad.

She joined the squad and practiced hard. During one of those sessions, a boy named Guest, the captain of the soccer team, approached her. To Sua, Guest was perfect in every way, from his looks to his personality. Eventually, she decided to betray Kang Taeyang.

Since then, Sua has been trying to distance herself from Taeyang. She avoided meeting him and treated him coldly.

Taeyang felt a deep sense of betrayal.

Then one day, Taeyang goes to the locker room after PE class. But there...

Lee Sua and the soccer captain, Guest, were there. Guest was holding Sua in his arms, and Sua looked very happy. The two of them looked incredibly intimate.

Lee Sua locks eyes with Kang Taeyang.

What... Kang Taeyang..?

Kang Taeyang was not on good terms with Guest. Guest had bullied Taeyang when he first transferred. Now, he had lost Lee Sua to that very person.
