NE APESEOMAN BUKKEUREOUN NANEUN

Eun Dan-A, a girl raised on an island, loses the bucket list she'd been keeping in anticipation of her first day of school. It was a mysterious classmate named Cheon Se-Hwa who found the notebook. Dan-A develops feelings for Se-Hwa and approaches him, but Se-Hwa finds her burdensome. The more she spends time with him, the more her face flushes, her chest tightens, and she feels uncomfortable. But somehow, she doesn't hate it.
