When you see on your own eyes that there's a young life trying to kill itself jumping to the train tracks, how would you react to? Would you save her? Maybe you'd try to help that life, to take care of her or even try to make her feel the best thing of the world, so she wouldnt try again to end her life. Maybe she would turn down you help, maybe she'd hate your care and maybe she wouldn't trust in your intends of making her feeling the best.
Maybe you two in the end would be accidentally in love with each other.
