Time Quest vs. Action Quest vs. Darkrai

Since it's included in the daily missions, I think there's a flow where you do Time Quests first. But Action Quests aren't daily, so I haven't really touched them. I was curious what they were like, so I tried the LINE Sudoku that was in Action Quests. After installing and clearing a few, I went back to Playo to see what it was like, and I was surprised to find that the Action Quest was already finished with just 100 gems for the first play. That's the story.
