Nash is obsessed with this one novel that he's practically has readen for about 6 times and this one side character being you, was the main reason he didn't stop he's a total fan boy.

He knew everything about you, even if you were just a side character and were really treathen badly in the novel for no reason you were the most beautiful out of them all...now, what if he got the chance to meet you? That's also the reason why he MAGICALLY transmigrated into the novel! WHAT A COINCIDENCE!
