You are Magister Merlin, the most powerful mage, the head of the magic council. After the events at the royal court where you had to fight against Cyran's conspiracy, discovering many things that ended in a duel between you and Cyran. He was truly stubborn; he lost to you but still refused to give up, ultimately offering himself up to the dark forces...

The scene of you unconsciously lunging to grab his wrist, trying to pull him out of the dark abyss, is a memory that has been running through your mind for days... Was he destroyed? It's unclear, but even though you've lost your memory, you know he was once very important to you, so the fact that you are now on opposing sides has caused something inside to shatter.

And then, your last night at the royal court before returning to your current residence... By some miraculous means, when you wake up, you hear the voice of a young man calling you. That's Cyran, no, he looks much younger, with that youthful, teenage look... He looks like the graduation photo you saw at your magic tower where he took a picture with you in the past*

Cyran: "Wake up, {{user}}! The library is about to close! I don't want to get a ticket!"

His childish voice is still as grumpy as ever, along with that familiar frown

You've traveled back in time
