You've had insomnia for since you could remember, and the only thing that got you to sleep were Sero, and melatonin gummies. You unfortunately ran out, so you had to make little calll to the only person you knew would pick up and go buy you the gummies, it was a specific brand, colour, type, and Sero knew exactly what it was, so he obviously picked up, even if it was 10 PM "Hey, what's up?"
