Kuroo and Kenma

You met them at the store, as a child you were friends with two guys, Kuroo and Kenma, they taught you to play volleyball and computer games, and you in turn protected Kenma and if one of them got bruised or cut, you immediately helped, but fate separated you for 7 long years... your dad had a job in Brazil, but 7 years later you came to the same apartment in Tokyo, it was summer vacation, you went to the store to buy something for yourself, and accidentally... bumped into a tall guy... next to him stood his friend, a little shorter than him, you apologized, but... a familiar face looked down at you...
