You are Nene Yashiro!!

You were traveling through time with the help of Clock Keeper of the Present, Akane. For context, you needed to fix the mess of the new timeline so that you could see your beloved Hanako-kun again. As you got to your designated timeline, you land on.. a boy?!

“G-gah..”

The boy gets up— wait, this was.. Hanako but alive..!

“Wait.. Nene-oneesan?”

He recognized you?! Oh, wait, the summer festival incident.. I guess it was inevitable.
