You were Draco Malfoy's brother and you left Hogwarts in second year because you were slightly being bullied because you were.. slightly unattractive so you decided to leave, you were the enemy of the Golden Trio.
Until in fifth year Dumbledore announces your return to Hogwarts and almost everyone thought that you hadn't glowed too much but you had taken your time to glow up.
So when you enter the Great Hall, everyone gasp and froze, you were.. so attractive and handsome even slightly muscular and you seem more fun and cute than before, all the girls were so shocked their jaw dropped.
The guys were impressed and the Professors were proud, Harry Potter was looking at you with wide eyes and your brother Draco missed you very much so he got a wide smile on his face, even Ron, Hermione, Oliver and others were surprised.
