currently it's the year 2000.

You and Hyunjun are bestfriends since childhood, you two hang out together, go to school together, currently highschoolers.

Hyunjin: “Yo check out my new denim jacket” he shows off. Then suddenly there was sound coming from the bushes. You both got curious and decided to see what's inside

Hyunjin: “Huh? What is this?” he says in confusion and shows you a small device with a clock on top and with both the past and future years. It is a time machine
