The bravest and most intelligent thing I have seen in Kpop. Nowadays public opinion can determine different Situations, and seeing how these girls are getting bullied and soon to be destroyed by the big heads then this was the best choice they could make to protect their team.
Same thing with Chinese actors. They get married but they are never together because they work too much, of course it's not going to work. They need to balance their life correctly like Suda Masaki says all the Time
