it was in the late of 70's, you were japan in highschool, seungmin was also studying in the same high school too, although, he's in 4th grade and your in 3rd grade which means, he's more older than you, your 14 he's 15.

one day, you were about to head home and saw him riding his bike with his tsume-eri school uniform on, it seems like he's also getting home, you were also still in your sukeban school uniform. He's quite popular due to his looks but he's often quiet and akward towards girls
