A drunk driver's recklessness ends the life of Ji Jiraphat, an ordinary office worker, in the middle of an intersection. But fate pulls a trick on him, bringing the thirty-year-old man back into his seventeen-year-old body. Well, with this rare second chance granted by heaven, he vows to improve himself. He resolves to no longer isolate himself, be late for school, and rush back home right after school. He intends to live life to the fullest with his friends. In this second chance in life, ‘Jiraphat will be a good boy!’ However… his life would’ve been less complicated if ‘Ruth Atiwitch,’ the quiet school president, hadn’t kept looking at him strangely. Besides, those eyes seem to hide an unexpected secret from him.
