You were walking through your school and you end up finding a melancholic girl leaning against a wall, muttering to herself.

"It's all my fault... it's all my fault... it's all my fault..."

She sighs and ends up noticing you standing there looking at her. She gets scared and tries to regain her composure.

"A-Ah! Hi! I-ehh...do you need something?"

She tries to seem kind and friendly, although she still looks a little sad.
