I have a hunch that Jiwoo won't talk even if they torture him and keep the info for himself until his last breath but I hope Kaiden will come before it gets to that point.
My guess is that the trio will notice Jiwoo's absence and will go to his house, run into the mess near his home, discussing about it, letting kaiden (in cat form) be aware of the situation at the same time. He will then transform and tell them not to run around (which they will not obey obviously) and sneak into the basement (not without noticing shinwha and the union ofc) freeing Jiwoo while Kaiden is kicking the ass of the two who dare to hurt such his pupil.
I would be content if Melissa ends up with Nine. Like he is sweet with a little fierceness that balances well with her personality. But I would be even happier if she ends up with Yuri. I really love Yuri, she is a little bit mischievous but sweet, and I love how she seemed to enjoy her life when she is with Melissa. If there is a possibility, even so slight, of a 3some, I would be in heaven!!!
After reading this chapter, what's going ahead make so much more sense now! And I'm not satisfied enough after all of the things that bastard did to El! He needed more beating seriously!
