Even tho most Kpop companies got rid of the ban most fans especially Korean fans are still bothered by it and will protest them to get out of the group, but at least there’s a lot of international fans that will support them.
I think Yak still has feelings for the girl, he lied about his status with Dee because if she knew, she will back away and he doesn't want that. I feel like he wants both of them as of right now and cant choose, even tho it looks obvious he is in love with Dee. Also when did Ter become gay? as he stated earlier in the drama he is straight or hes always been gay and lied/didnt discover it yet? idk but next ep Yak better forget about the girl and confess already. But Ter will def become a problem.
