Historical vs Creative Freedom

I’m going to HOPE that the author takes plenty of creative freedom and goes with the route where Mitsuhide ultimately uses the huge fire that break out as an excuse to spare both Nobu and Ranmaru. Maybe he betrays Nobu at first, fights him, wounds him, but ultimately loves him too much to actually kills him. Mitsuhide has a change of heart last minute, tells them to leave and to never come back, using the excuse that their bodies perish in the fire. Manga Mitsuhide seems to love and respect Nobu greatly, I cannot fathom he can actually pull the trigger to kill him. Historically the great fire took down everything, the real Mitsuhide never did find Nobu and Ranmaru’s bodies. There’s HOPE for a happy manga ending ╥﹏╥
