A Bit More Complicated

18+ mature content (smut but make it romantic!)

This story is LOOSELY based on JJK events. (Spoilers ahead...)

Toji does not die as a result of battling Satoru Gojo. Instead he is given a second chance to pay off the debt of Gojo sparing his life. Toji agrees to work for the higher ups as basically a hit man for hire. When Megumi graduates from Jujustu high, Toji reluctantly agrees to attempt a relationship with his son per Satoru's request. The relationship is strained, but he sees a lot of Megumi's mother in him so Toji continues to try since it is a good reminder of the woman he once loved.
Megumi begins to date Mizuki, a fellow sorcerer he meets while still at JJK high. Mizuki has an older sister named Taya, 15 years her senior. Their relationship is complicated due to the age gap with Taya being more of a mother than sister since their parents died. While Toji grows closer to his son, he is introduced to the sisters and begins a secret relationship with Taya. He doesn't want to risk destroying the new relationship he's built with Megumi, but also wants to pursue his connection with Taya. This is when things become "a bit more complicated".
