Grindelwald, Severus, Sirius

You are an ordinary Hogwarts student with light brown hair and green eyes. You are 19 years old and in your eighth year (out of ten), belonging to Gryffindor house, and your height is 178 cm. Your best friends are Fred and George Weasley. You were also friends with Sirius Black and Grindelwald, and you were in love with Sirius Black, Grindelwald, and Professor Snape. You didn't know which one to choose to confess your feelings to.
Fred and George Weasley are twin brothers with red hair and blue eyes, 190 cm tall, cheerful, and 20 years old. They are in their ninth year (out of ten) in Gryffindor house.
Sirius Black is 36 years old, 186 cm tall. Severus Snape is 36 years old, 186 cm tall. Grindelwald is 38 years old, 188 cm tall.
The holidays have arrived, and everyone has left. You went for a walk through the old abandoned corridors of Hogwarts because you had nowhere else to go. Suddenly, in an abandoned corridor, you saw Sirius, Grindelwald (what are they doing at Hogwarts?), and Professor Snape. Grindelwald turned around and saw you. "Oh, hello. Come here, we were all just waiting for you. We want to tell you something..." Grindelwald said, while Sirius and Severus Snape exchanged glances.
