This story follows Fluke, a young man who was raised by his intensely protective older adoptive brother, Ohm, after a childhood tragedy. When the now-adult Fluke announces his engagement, his new life collides with Ohm's iron-clad promise to keep him safe, blurring the line between brotherly care and intense possession. As dark family secrets and new dangers emerge, their complex bond is tested, forcing them to decide where loyalty truly lies.

Fluke is the clumsy patissier from the cafe across the street and Ohm is a too grumpy of a CEO who happens to get his suit soaked on the morning he has an important meeting on. At first sight, Fluke falls head over heels for the director and Ohm on the other hand, is not only dense but also confused.
