Rain lashed against the windows of Liam's tiny apartment, mirroring the turmoil brewing inside him. He hadn't touched his guitar in weeks, a stark contrast to his usual routine. His fingers, usually nimble and eager, now felt clumsy and lifeless. He slumped on the worn sofa, the silence amplifying the dull ache in his chest. A letter arrived that morning, hand-delivered and bearing a name he didn't recognize: Evelyn Carter. It contained a birth certificate and a request to meet. His father's name was printed on the document, and a wave of nausea rolled through him. He tossed the letter onto the coffee table, the paper landing crookedly, just like the world felt.
