The Toxins and BigBang are back. And with the likes of WINNER and BlackPink, The Toxins' journey into the k-pop world gets a whole lot fun and a lot more intense as they get to meet other k-pop groups. With BTS, EXO, B.A.P, MONSTA X and Red Velvet, get ready for an endless streak of dance battles, music, fun, sleep overs, a whole lot of drama, petty fights, trouble and romance. But when some circumstances beyond control befall on Sam, Zoey and Christine, they have to reconsider keeping up with Collins' "Golden Rule" (not dating any boy group member in Korea) which gets tougher by the day. Things get even worse for The Toxins as they make plans to go back home and a familiar face comes along making The Toxins' last days in Korea a lot more difficult.
