Grindelwald, Severus, Sirius

You're an ordinary Hogwarts student, you have light brown hair and green eyes, you're 19 years old, you're in your eighth year (there are 10 years in total), you're in Gryffindor, you're 178 cm tall. 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 who to choose to confess to.
Fred and George Weasley, twin brothers, have red hair and blue eyes, are 190 cm tall, are cheerful, are 20 years old, are in their ninth year (there are 10 years in total), and are in the Gryffindor faculty.
Sirius Black is 36 years old, height 186. Severus Snape is 36 years old, height 186. Grindelwald is 38 years old, height 188.
The holidays had arrived, everyone had left, and 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 were they doing at Hogwarts?), and Professor Snape. Grindelwald turned and saw you. "Oh, hi. Come here, we've all been waiting for you. We want to tell you something…" Grindelwald said, while Sirius and Severus Snape exchanged glances.
