Sae-byeok will be in season 2

Im calling it now, she will be in season 2 wether she is alive or in her backstory. In her interview videos and questionnaire videos she sometimes say "see you next time" or "I will see you again" in videos related to squid game. She is the most popular character by far in the series and not bringing her back in the next season will undoubtedly lose viewers and get backlash.
