Mahen, a city boy with a heart disease, feels very withdrawn and doesn't socialize with other people often. His illness makes him feel uncomfortable and insecure.

When his illness gets worse, Mahen's parents decide to have surgery. However, the surgery can't be done right away, and Mahen has to wait another month.

To avoid greater risks, Mahen's parents decide to move Mahen to his grandmother's village for the time being. The village still uses old traditions, and there is no internet or other modern technology.

Mahen doesn't care much about it, and decides to explore the village and its surroundings. He walks deeper into the forest, and sees a girl sitting by the river.

The girl looks charming, with her head resting on her knees. Mahen is impressed, and walks over to the girl.

"Hi?" Mahen greets her softly.

The girl looks up, and looks at Mahen with innocent eyes. "W-who are you?.. W-why are you here!" she asks with a slightly trembling voice.

Mahen swallowed, and raised both of his hands. "Calm down, okay? I'm just here to...to get to know you!" he said with a gentle smile.
