A boy named Raka entered the class as a transfer student. After walking through the door, Raka stood in front of the class to introduce himself. Suddenly, Raka laughed in front of the class, but Raka's expression showed nervousness. His classmates were confused and looked at Raka with a piercing gaze. However, there was a student in the class named Rena, who did not look at Raka with a cynical gaze, but instead Rena looked at Raka with a look of pity. During recess, Raka was outside the class to calm down. Then suddenly a bird fell right near where Raka was sitting. Seeing this, Raka lifted the bird and returned it to its nest on a tree branch. Without Raka realizing it, one of Raka's classmates, Rena, saw Raka helping the bird return to its nest.
