やけっぱち世界征服

The hero, an archer and I have departed on a journey to defeat the demon king. At some point, I realized I'm so in love with the hero my heart just won't stop pounding! I don't even care about defeating the demon king anymore!

I gathered my courage and told him how I felt, but...

"I love you too. Like a little sister."

...wait, what? Little sister? Are you kidding me?!
