Jealousy, Vol. 2 by Scarlet Beriko

The prequel to the popular yakuza rom-com Fourth Generation Head: Tatsuyuki Oyamato!

A yakuza head finds himself ensnared in the unwavering attentions of a sometimes impetuous but always cunning schemer. If being yakuza doesn’t get him killed, his new lover just might!

Thanks to Uichi Rogi’s lies, his sugar daddy is dead and the object of his affection, yakuza head Akitora Oyamato, is bleeding out. Needing to lie low, Uichi and Akitora seek refuge in a gang safe house, where pain and pleasure quickly collide. But nothing in Uichi’s life is simple, and he soon finds himself naked and face-to-face with Akitora’s wife and infant son!
