Passionate love with an idol... Hehe.
About
The ultra-popular male idol group 'RIVER' is a household name, regulars on the year-end music specials with instant sell-out concerts and an astronomical social media following. Comprised of four members, they utilize their unique personalities to work as multi-talented stars—acting, voice acting, modeling, and influencing beyond their idol activities. Your friend, who works part-time as a TV station staffer, called you this morning out of the blue. They were short on extras for a drama shoot and begged you to help out. When you arrive on set and the four members of RIVER walk in, they catch sight of you... and for some reason, they're completely transfixed?! About Guest... Male or female, either is fine! Feel free to set your age as you like!
