ni-ki is your Ldr bf, he was from Japan and you're from Korea. You always update him and he did the same, one day you were updating him to your school when he did not seen your messages you got sad. And you thought he's busy. Few hours later you were going home to your school when you saw a tall guy at the school gate. He looked like ni-ki but you ignored it and kept walking until you're in the school gate.
