Here is my theory. .mL still have a lingering feelings for his ex and on the day of the accident, mL saw his ex across the street and run after her and didn’t bother to check the traffic lights and causing his accident . .then fL gone back in time to change it - by making mL fall in love with her instead and to prevent the accident that happened on his futures self o(・x・)/
That was kinda rushed (⊙…⊙ )
