Will you be able to survive if you're not allowed to sweat? Will you be able to endure without exercise, strong emotion, hot ambient temperature, spicy food, and not taking a hot bath throughout the winter? Jasper is his name.  A delicate boy who enjoys being alone while  listening to a gentle melody and gazing at the sky, appreciating the beauty offered by the moon and stars in the universe. He doesn't like heat-related things. In fact, he's avoiding it for the sake of his health because he's suffering from rare allergies called cholinergic urticaria or HEAT allergy.  While going through that circumstance, he met Elanor. The girl who provides a dazzling light amid his darkest night. LET THE LIGHT SHINE UPON THE DARKNESS.
