A rational genius who was emotionally indifferent and unable to perceive emotions due to a congenital disease awakened the ability to "smell emotions" after a near-death experience. He has become a walking emotional meter, able to judge the truest mood of the people around him through smell. He originally wanted to use this ability to advance in the workplace, but he accidentally became the mastermind behind an "emotional healing APP". He can tailor prescriptions with precision, but he can't cure himself. Until he was forced to learn a subject never recorded in textbooks in order to save a girl who was suffering from severe depression: the ability to love.
