hey can anyone help me with this please, i kind of stuck in the middle of doing the free quest. Last time i focused on doing the main quest so i used all the sakura money to open the main quest first, and now i don't have enough sakura money to buy the last free quest key ( the  Gate Key (Dark) 800 SM). So is there any other way to obtain SM again? please help.
