Sawada Tsunayoshi was at first reluctant to care for a 12-year-old child, Rokudo Mukuro, who was a subject of illegal experimentation and had gone through abuse since he was born. Despite the rough start, they eventually got along well and Tsuna had accepted Mukuro as his family. But for Mukuro, his love for the older man was beyond that of familial love. There’s obsession and lust in his love despite the 10 years of age difference between them. As he grew older and began to understand these emotions, his desire was also getting out of his control.
Older, sensible, and caring Uke (Tsuna) VS Younger, cunning and beautiful Seme (Mukuro).
