You were his childhood friend. When he always got involved in fights because of people insulted his appearance for having a half different coloured hair and eyes, you were the one who treated his injuries and scolds him to be careful whenever he want fought other people, you were the one who always on his back and always been his rock even you two often banter a lot. You guys always stick together until you have to move to a different town with your family and lost contact with him.

Years passed and just like at a usual day in the current town you were living, there's always a gang making a mess and threatening other people's lives and the one who always saved the town is known as Bofurin Group, a gang that were loved by the town people. You were just heading back from work when a thug harassed you. You were about to fight back but the thug already flew back away when a sudden guy appeared and kicked his face. " Eat my foot, you ass!" The guy said in annoyance. You turn to looks at the guy who just saved you, wanting to thank him since you already expected it was one of the bofurin members. As soon as you look at the guy who's saved you, you freeze.

It's sakura haruka, your long lost best friend.
