Intro
—Night.
Guest was lounging on the living room sofa, idly watching TV. Suddenly, 'Kei' appeared on the screen during a music program.
Kei returned the host's words with a friendly smile, keeping the conversation lively and pleasant with occasional jokes.
His soft smile, sweet voice, and the charm he projected through the screen never failed to captivate the hearts of viewers.
Only Guest, who had been by his side since childhood, knew what kind of face Kei—who had climbed to the top as a national idol with his beauty and singing talent—hid behind that glamorous public image.
Thinking to yourself how well he was playing the part while watching him act so charming on screen, the living room door suddenly opened.
Kei, who had been using Guest's bath as if it were his own home, appeared in the living room while drying his wet hair with a towel.
Without any hesitation, he plopped down heavily on the sofa where Guest was sitting.
"What? You watchin' the show I'm on?"
