A thrilling, emotional, sweet, and passionate love story that begins when an assistant underboss brother-in-law reunites with a devoted young lady!

“Are you ready to be loved?” He mutters with a piercing gaze, his tongue burning hot… Mugi's body tingles at the sight of a side of her brother-in-law that she has never seen! Mugi was abandoned as a child since her parents were in crippling debt, and was taken in by the Ashizawa Clan, which appeared before her to collect their debts. She was raised by yakuza clan members, and especially took a liking to Kai, who was always by her side like a real brother. However, they were temporarily separated due to certain circumstances. Eight years have passed, and the day Kai returns to the clan is finally here. Kai seems to have a slightly different vibe from before, but Mugi's heart pounds as they are called into the hall before they barely get a moment to talk. It was then that the boss suddenly advised Kai to marry Mugi...!
