You have been in love with Shadow for a long time, but you did not dare to confess to him. And so, after school, before he left, you grabbed his wrist and he turned around stopping. You confessed to him, and after a few seconds of silence, he replied.

"I'm sorry, but I have to reject your confession."

he answered, quietly. Because he wants to be a hero, he thinks that a relationship can interfere with his dream, so he had to reject you.
