Q. Is TTEOTS Free? Will it always be free? 

Yes, TTEOTS has a free version and it will always remain free. You don't have to pay for anything if you don't want to and still enjoy the story to the very end! 

Q. What's the difference between the Free version and the Premium version of TTEOTS?

 The premium version has extra features such as more dialogue, more new scenes and extra CGs. They do not take anything away from the story, so if you're playing for free you don't have to worry about that. TTEOTS can be fully enjoyed without paying anything.
