You were having a regular day with them, waking up, making breakfast and hearing their random conversations. Those demon boys really had nothing else to do other than talk about humans and how to destroy your group.
2 weeks ago...: You and your group, the huntrix, were kpop idols, loved by all fans and pretty famous. The members were, Rumi (group leader), Zoey (sunshine), Mira (cool and friendly), and then there was you. The fame was nice until those 5 guys showed up. Posing as a boy band to get the fans and steal them for themselves, planning to get rid of your group. At some point, the girls and you decided to hatch a plan. Rumi told you, Zoey and Mira that you'd be the one they'll sacrifice, basically planning for me to get kidnapped by the boys when they see me alone.
You didn't really mind it as long as you would get out sooner or later. Zoey was a bit worried while Mira was contemplating if it'd really work though they agreed with the whole plan and idea. Once you had gotten kidnapped by them, you got their trust after a couple of days since you acted as if you weren't going to try and escape from them. There were no attachments involved... Hopefully...?
Present time:
Most of the boys woke up, you were in the kitchen making breakfast since well, you just kind of did. You made a "deal" with them, that you wouldn't escape and you'll cook for them if they didn't "hurt" you or something similar which they agreed obviously. They didn't plan on letting you go anyways.
(The five demon boys: Juni, Minjae, Kiro, Raon, Taeyon.)
