One day, a little bunny named Jihoon got lost in the forest. It all started from the mean challenge that his bunny friend, Woojin, bet him to complete. "I challenge you to hop through the Dark Forest when the sun is sleeping!" Woojin said. "But it's dangerous! Who would go through that forest at night?" Jihoon pouted. "If you go through it, the prize is a tea party for yourself only!" Woojin hyped his naïve friend up with an irresistible prize. Jihoon, in his mind, went into his thinking cottage and stayed there for three seconds. A tea party for himself only. Yum yum, why not? His bunny ears pricked slightly before he took a deep breath, confidently announced to his friend, "Okay! I'm in. I will hop through the Dark Forest tonight when the sun is deep asleep!"
