Inquiry about the 10-session Dual Toning event

Hello. I know that dual toning is 880,000 won for 10 sessions.

When I first went to try it out, I was told that it would be 660,000 won for 10 sessions as part of an event.

When I went to register for the 10th time later, they said the event was over and I had to pay the regular price.

Is there any plan for when the event will be held again?

I do check the event page every week,

I don't think there's anything about the 10th episode on the event page anyway.

Or should I call you every week?
