At first day of their final year in high school, Singha was waiting for a bus and had seen a woman fell down. He helped the woman and rode a bus to go to school. They had two new classmates, Lam and Mituna. Mituna got late from class at that time but was excused because she was new from the school. She sat beside Jazz and in front of her is Kanda whom she became friends with. At first, Singha and her pals mocked her for being so silent.
