His Girl { Chihiro x Haku }

Chihiro and Haku are best friends at young age. At around middle school, when they were walking on a street , they were both crashed by a car and lost their memories. Both of them lived their lives without each other from that day on since they do not remember anything. What will happen if Chihiro and Haku meet at high school again? Will they remember the past? Will they become friends? Or will they become even more than that? I do not own Spired Away or Chihiro and Haku.
