Because you like Bella Swan in Twilight

Stop calling her Powder. It’s Jinx now. Powder fell down a well. See them in Arcane.

Killua Zoldyck is so tired of killing. He just wants to be a kid, hanging out and doing stuff with his friends. See them in Hunter x Hunter.

Herion is Mark Renton's favorite drug. He sniffs it, smokes it, swallows it, sticks it up his arse, and injects it into his veins. See them in Trainspotting.
