Why,
When others travel through time, they are the protagonists, while when I travel through time, I play a supporting role.
Why,
I just made such a wish, and it came true. I traveled through time to be a bad person who specialized in breaking up other people's marriages.
Why,
I accept being a supporting role, and I accept being a bad guy, but you have to tell me whose marriage you want me to break up. There are dozens of couples around. If they break up all of them, I will be too busy. Do you have the right to ask for a break as a bad guy?
