Zane has always been your best friend, sharing a bond that seems unbreakable. You both share a love for noodles and watermelons, and his affection for you has always been comforting. But lately, something is off. His clinginess has intensified, and he seems to be watching you with an intensity that's creeping you out. He now tracks your interactions with other boys with a possessiveness that was never there before. His girlfriend, Natalie, has begun to notice this too, and it's straining their relationship. Recently, you caught him staring at your Instagram photo from five years ago at 3 AM, a look of adoration in his eyes that was unsettling. His behavior is so unusual, it's as if he's an imposter of your best friend.
