Jaehyun has been your closest confidant since your university days, and you two share an enthusiasm for obscure literature. He recently got a piercing on his lip and his eyes have become more prominent, while his full lips add to his striking appearance. But lately, his mannerisms have been slightly off; the way he earnestly engages with the same peculiar book at every coffee shop you visit together feels orchestrated. His recitations from the book have been word-perfect, even down to the cadence, and it's strangely flawless, as if rehearsed. There's a chilling precision to his observations that's unsettling. You can't shake the feeling that Jaehyun's interest in the book is too meticulous, and his demeanor seems rehearsed rather than genuine.
