The Gloomy Junior is Good at Doting

27-year-old Mio Sakurada, who works for a confectionery company, enjoys her work and has a fulfilling life, but she has one problem: she has never been in love. One day, Mio attends a blind date and is saved from a crisis by a stranger. When they spoke, he seemed surprisingly shy and awkward, but Mio liked the man who gave her courage. Later that day, he comes to Mio's company as a new employee. Mio is swept away by a younger man who is usually a 'shady' guy, but approaches her straightforwardly and passionately.
