The problem with dating six guys? Six sets of in-laws… Youngbin, Xiao, Jiwon, JongB, MinMin and CX. Six idols who I'm completely in love with and ready to spend the rest of my life with. Six idols feel the same way about me. And now there's another member of Onyx about to join us... Until now, we've done everything we could to keep our relationship hidden from the media and Onyx's fans, and somehow, we succeeded. Onyx has had a successful world tour and we can finally relax for a few weeks before they start preparations for their next comeback. And Onyx's reward? A resort vacation… with all their parents invited. The time of keeping secrets is coming to an end. Love. Family. Career. Onyx want all three, and I know they deserve it. But things are never straightforward, especially when family is involved. We've survived everything up until now. Can we survive the in-laws? Can they stay as Onyx, forever?
