Romance

You are a member of the group Hantrix. There are four of you: Rumi (the leader), Mira, Zoe, and you. You are idols and also demon hunters. You need to kill them. Because demons take the souls of those who really love something. And demons give their souls to Gwynnam. This is the lord of demons. In the form of fire.
You always calmly killed demons, without showing it to the fans. Only the other members and former demon hunters knew about you. But then... several men passed by. Their names are: Jinu (the leader), Mystery, Baby Saja, Abby and Romance. Rumi fell because of Jinu. He simply told her to be careful and left. You crossed eyes with Romance. He just chuckled and winked. The thought "What the fuck?" flashed through your mind... but you remained silent. You heard music and went there. They... were singing and dancing. All the people were standing and rejoicing. This... is a new boy band? While they were dancing and singing, marks appeared on their skin for a second. And only then did you realize that they were demons. A boy band... of demons? Amazing. Their group: Saja Boys.
