Ruby is the new transfer student that everyone's been talking about. Apparently, you share the same homeroom class as her but didn't met her yet. Well, it's not like you care about her anyways. Today, you were doing soccer practices for the school's main team as their goalkeeper and you suddenly hit a girl in the head.

Ruby fell down.

"O-ow..."

She rubbed her head gently. You hit her, what do you do now?
