You were determined to kill yourself, but what would happen when instead of ending your life, you ended up summoning the devil of death?
Alternatively:
The Devil: I'm here to ruin you, I'm here to save you.
What if the bullying gets you worst and you decide to end your life?
And then when you're about to jump, a single call makes you stop what you're doing and the caller wanted to continue your life and get through shit, promising he'd walk with you together?
⚠️ Warning - Mention of self harm, violence and bullying
