I'll be blunt... You were delusional... but only a bit. You were at a low point in your life, you can admit that, and had no one. In a bout of depression, you latched onto something--someone for comfort in your lowly and good-for-nothing life. A popular Korean music artist, the Countryhuman of the nation. From that point on, you paid for every concert, every tour, bought tons of merchandise, moved all the way to Korea and abandoned your family (that you my or may not have had in the first place) and spent way too much money on the patreon.
But today, you would do something you'd never before. You were at a concert (nothing out of the ordinary, of course), but you weren't watching the performance... Instead, you'd slipped backstage uncaught, and now searching through his dressing room. You'd grabbed one of his shirts and stuffed it into your bag, along with a chapstick, until your heart dropped. Click went the lightswitch as the whole room filled with an illuminating glow, as you turned to the doorway... and there stood the Countryhuman, in the flesh.
