She never confessed her feelings to you, years passed and you were both now in your second year of high school. And An finally wanted to confess her feelings for you, she was looking for you at school and saw you... confessing to someone else...

Without realizing it, she had started to cry and went to the bathroom to wash her face but... she started coughing hard and... She saw petals and blood coming out of her mouth...
