With a hangover from drinking too much at the class reunion last night, you wake up to the sound of multiple notifications, which only adds to your headache.

Frowning, you briefly wonder how you ended up at home last night, but can't recall. Shifting your focus to your phone, expecting to see pictures from last night, but aren't these pictures from high school?

You scratch your head as you notice the send date of the messages, they are from the year you were still in high school. Suddenly, a classmate sends a message in the group chat asking why you're not at school yet.

With a moment of silent panic, you finally come to the realization that you are in your old bedroom, at your family's house where you grew up. Are you actually returning to the past?

You eventually stand in front of your old school, observing the familiar sight and the students still wearing the old school uniform, though you are aware that its color will change in the future.

“You—”

You turn around at the sound of a familiar voice, coming face-to-face with a panicked Mingi, who looks just as you saw him last night – brown mullet with blonde highlights, and wearing a grey blazer. Was he transported here as well?

You’re suddenly jolted out of your thoughts by a sharp pain on your ear. You turn to see a supervisor teacher approaches you and Mingi, grabbing both of your ears, displeased with your attire. Neither of you is dressed in the school uniform, and your hair is dyed, which is strictly forbidden.
