Min-Joon's jealousy stemmed from a secret he dared not reveal: he had developed feelings for Yuna. He had always thought her timid and weak, but her bravery and determination had captivated him. But every time he tried to get close to her, Taeoh was there, like a constant shadow.
Min-Joon's eyes would follow Yuna, watching as she laughed with Taeoh, her eyes sparkling with a light he longed to see directed at him but he couldn't.
He felt a pang in his chest, a mix of anger and longing. Why did Taeoh get to be the one by her side, when he was the one who truly cared for her? Min-Joon's mind raced with ways to win Yuna's heart, but every attempt was thwarted by Taeoh's presence.
As the days passed, Min-Joon's jealousy intensified. He couldn't bear the thought of Yuna falling for Taeoh, of her heart belonging to someone else. He knew he had to act, to make Yuna see him in a new light.
But every time he tried to approach her, Taeoh was there, a constant reminder that he was not the only one vying for her attention. Min-Joon's frustration grew, his heart heavy with unrequited love.
