Help, please? I'll give you three answer props if you do :)

I'm writing a story called Immortal Magic and it's about a boy named Darren who is all "popular" and "cool" and "hard" and he finds a girl named Willow in the pond/Lagoon in his school. Turns out Willow is a witch from the medievil ages. (idk how to spell) and she's looking for an evil "daemon" named Tryant, who takes the form of an owl and can influence people to be angry/happy/confused etc... and can influence some Dark Magic. Darren finds this out later because Willow is still afraid of anyone trying to excecute her for being a witch. Earlier on, another witch named Forsythia tells him he's something called The Wanderer, who is meant to be a help when a time of darkness is upon them.

But I'm thinking, should they go exploring to try and kill Tryant or should it come to them??? And should there be a sequel or should they die at the end? And should they fall in love?

Help please and I'll give you three answer props.
