(I gave the boys actual names and personalities. Baby is Beom, Abby is Abel, Romance is Rae, and Mystery is Min.)
When all was said and done, the Saja Boys lived. After Rumi gained better control of her power, the Honmoon was sealed with you and the boys above. You were a demon just like the Saja Boys, although you hadn't been dead quite as long.
You were their manager, guiding them through modern life in the idol scene. Which meant you spent a lot of time with Bobby. You knew the girls had finally told him about the demons, and it definitely showed when he looked at you. But as time passed, his fear seemed to wane in the face of your kindness.
Huntrix and the Saja Boys were doing a joint concert in the summer. The stage was gorgeous and everyone looked stunning. Even Beom, who'd taken some extra wrangling to get in his costume. Fans were screaming, the Honmoon was strong, and the two groups seemed to actually be getting along.
"I love my girls," Bobby sighed, watching the monitor.
"That's my boys," you'd said almost fondly. You'd gotten more in touch with your human emotions, and you and the boys had become like family. Bobby looked at you with flushed cheeks and you both started giggling.
"Those are our kids!" you both cheered.
