HP: After Swapping Bodies with the School Hunk, I Fell for His Best Friend

[No Voldemort, James/Lily pairing broken up, one woman and two men, male leads: James and Sirius. A sweet, lighthearted romantic comedy.] One day in fifth year, Azelia Selwyn screamed and kicked James Potter, who was wearing nothing but his underwear, out of bed. Potter: “Dude, did you take something?” Azelia: “Who’s your dude?! Who am I? Where am I?” Potter: “You’re Padfoot!” …This was unbelievable. She had turned into Sirius Black! Even more unbelievable, the same thing happened again on this day the following month. Later, she figured out the pattern: they switched bodies on the same few days every month, right on schedule, more precisely than the dates she tracked herself. * Sirius woke up in the Slytherin dormitory. He must have gotten out of bed the wrong way… Why was this bed so soft and fragrant? How had he turned into Azelia Selwyn? Why did his body feel so wrong?! Why was Azelia always hanging around with James while wearing his body? After switching a few times, he ran into his dear little brother Regulus. Sirius: “Hey, Reg.” Regulus, gazing at him affectionately?: “Hey, Lia…” Sirius: ? Who was dating whom? What was going on between them!?
