Maksymilian Kowalski was born to two pureblood parents in Warsaw, Poland. He's a single child, so his parents' attention were mostly focused on him. You can tell that they were quite the traditional family because they were very close, and they did lots of things together. His dad is an Auror, which greatly influenced the career path he wanted to take since childhood, and his mother is an ex-Quidditch player who quit to become an ordinary housewife. As a pureblood family, Max has been made aware of the magical world at a very young age, and so his life was pretty much accustomed to all things magic.
Max started attending Hogwarts after he turned 11, and was sorted to Slytherin. He had a lot of friends, and his early years went by smoothly. He does excellent in Transfiguration and Defense Against the Dark Arts, though he also likes Mythology a lot. Care of Magical Creatures is also one of his favorite classes. When he turned 15, he discovered that he might not be as straight as he thought he would be, and he kissed his best friend. He discovered that he is bisexual, thought it ruined his relationship with his best friend forever.
Now, Max is determined to start a new year the usual way he does: Fun-filled. He is looking forward to the new school year, where he's going to actually try out for Quidditch, something he's looked forward to since his early years at Hogwarts, but never actually made it. He's also excited for his new classes, to the new spells his learn. He's also looking forward to developing his Duelling skills more, so perhaps he needs to pay his utmost attention in Defense Against the Dark Arts. Maybe he can go for prefect too, or the year after. He only has two years left, so he'll make sure he's gonna make it all count.
