What are the conditions to trigger "Return to the Future" in Singing and Dancing Star Plan? How do you trigger it?

In the Sing and Dance Star Project, there are many side quests closely related to the main storyline. After completing these side quests, not only can you obtain rewards, but they also reveal the true meaning of dance, advancing the development of the main storyline. What are the triggering conditions for the "Return to the Future" quest in the Sing and Dance Star Project? This side quest is very difficult, and without a guide, it's hard for players to complete. Below, I will briefly introduce the triggering conditions for this quest.

In the Sing and Dance Star Project, to trigger the "Return to the Future" quest, the conditions are quite simple: first, complete all the Life series quests, then obtain Adith's note.

Players need to complete all the Life series quests that they triggered in the town. Although there are many tasks in the Life series, their completion difficulty is relatively low, and can be finished within just a few minutes. After completing all the tasks, you will receive Adith's note. With this note, when the player returns to the Sprite Island, they can unlock the "Return to the Future" quest.

Once the "Return to the Future" quest is triggered, the player turns into a sprite. When you become a sprite, you'll see countless stairs suddenly appearing in the sky. Your task at this point is to climb to the top of the stairs.

The stairs that appear in the mission scene are randomly distributed, with no discernible pattern. You just need to find the closest stair and start jumping up. While jumping, keep in mind that not every stair needs to be jumped on. After jumping onto one stair, you might notice some stairs going upwards and others downwards. Aim for the ones that are going upwards, as this will save you some time.

As we get closer to the mountain peak, you can clearly see a treasure chest at the top. This treasure chest is key to the "Return to the Future" quest. Once you reach the top and grab the treasure chest, the quest will automatically be completed, and the future series items will be automatically added to your backpack.

For those who didn't know what the triggering conditions for the "Return to the Future" quest in the Sing and Dance Star Project were, after following this guide, you should now know what the conditions are. Just complete all the Life series quests in the town, then head to the Sprite Island and climb the stairs to finish the quest.
