I fell for you out of my own free will. So if I ever fall out of love, that'll be my own decision too.
The peaceful world I'm fighting for is one where everyone has a smile on their face, not one where I have to pretend I didn't see you make my friend cry. I don't think that kind of peace is worth fighting for. And I don't think it's worth making sacrifices to achieve it.
No matter what troubles you shoulder, remember that in time, things will change. You shouldn't blame yourself when things don't go your way.
You don't have to be reasonable when you're in love.
