Thicker Than Water (2018)

Yuria, a dedicated owner of a small printing business, struggles to capture the interest of Kazunari, a courteous but distant client. His attention is instead drawn to Mako, Yuria's charming but scatterbrained younger sister who also works for her. Complicating matters, Kazunari juggles responsibilities with his brother Takuji, a rough-around-the-edges man just out of prison and currently living with him. As relationships intertwine and tensions rise, Yuria must navigate her feelings and family dynamics while trying to keep her business afloat.
