Yeah, Zero is busy doing business, haha but she will be back. If you have reached the true ending of the game ( Where the MC hugs the mysterious balcony girl) then you have known that a new world is being created making the suicides less important after all and CC did explain near the end why she thinks so many people ( including the CEO's daughter) come to this village to end their lives. It's a parallel to the ''truth'' of their world.
