Heartbeat Hide and Seek, Game Over if Discovered

That day, driven by survival instinct, Su Mo, who had been a boy for 18 years, accepted an SSS-level mission from the challenge system called “Heartbeat Hide and Seek, Become a Beautiful Girl if Discovered” – a crossdressing task. He originally thought that with his 18 years of experience as a male, he could easily handle this mission. After all, a boy pretending to be a boy – did he even need to act? But after accepting the mission, he felt his body undergoing staged beautiful girl transformations as the mission progressed. Looking at the pure school belle, mature student council president, scheming loli… who had coincidentally gathered around him, Su Mo couldn’t help but worry – could he (she) really succeed in this game of hide and seek?
