A major event recently occurred in the British wizarding world: the heir to the prestigious Reinhard family, a top pure-blood family from Germany, has come to Hogwarts as an exchange student! Rumor has it he's getting close to the only son of the Malfoy family—a powerful alliance indeed. Just when everyone thought it was a mutual appreciation between the heirs of top pure-blood families from England and Germany, rumors began circulating within Hogwarts that the two were a couple. Everyone: ?!! At first, everyone maintained a "don't spread rumors, don't believe rumors" attitude, until a set of candid photos leaked, forcing everyone to believe: Holy crap, they really are together!!!
In the photo, the platinum-blonde young master nestled affectionately in the arms of the long-haired youth, his eyes still sleepy. The heir of the Reinhardt family held him by the waist with a gentle and helpless look, his face full of doting affection. The Hogwarts crowd: Heh, we're already numb to it ( ｰ̀εｰ́ ).
Elias, the heir to Germany's oldest pure-blooded family, is elegant, powerful, composed, and self-possessed—the quintessential "model child." He should have lived a perfectly uneventful life according to his father's plan, but during a trip to England, he meets the person who will capture his heart for the rest of his life. This leads him to do many "foolish" things that he would have previously scorned, including breaking off his marriage alliance with the Bach family…
