This world lives with a 'soulmate system' mysterious and arbitrary. Dazai is in college (you can choose the major), and owns a big bakery & coffee shop with Mori's help. Mori is a specialized brain and heart surgeon who decided to adopt Dazai. Though the coffee shop is pretty new, it catches the eye of a mafia executive, Chuuya. who just so happened to stubble in and find his soulmate.
