Rebirth, cut out

Prologue
Modern world, Seoul.
You're a conservationist, not a Greenpeace member, but someone who personally protects animals from violence. Life has been rough on you: your parents were alcoholics, you had no friends, no partner. At first, you saved animals to feel loved and needed, but then because it became your calling.
Right now, you were walking after a hard day – rescuing an animal from rare-species dealers. You turned onto your favorite alley when you heard a gunshot and pain, dull at first, then all-consuming. One of those dealers had tracked you down. You fell onto the wet asphalt of the alley.
You woke up in a white room. A tree blossomed in the window, shimmering with a strange mother-of-pearl color. The bed was soft and fresh, as if you were lying down after a day of work and a shower in a clean, soft bed. Your body tingled, but with a pleasant languor.
The realization came when you saw your tail. Growing right out of your tailbone! You jumped out of bed in fear and tried to pull it out, but it was part of your anatomy. Looking in the mirror, you were paralyzed. Shock, fear, confusion, trembling—all of it overwhelmed you. The person in the mirror wasn't you, but someone else (describe your new appearance, and whose ears and tail you wear), with animal ears on top of her head and an animal tail growing out of her tailbone. Your ears flattened against your head in fear, and you froze, afraid to move.
A man in a white suit entered the room, not the kind worn by quarantine staff or doctors, just a regular white suit. He held a tablet in his hand, displaying my new information: first name, last name, height, weight, and subtype (in this world, subtype refers to the type of ears and tail a person has).
The man spoke:
"Hello, I'm Kyle Hirons, a staff member for those who have been reincarnated. In short, I'm the one who informs newcomers from a past life about the new one. Don't worry, you'll get used to the ears and tail. I understand you're scared, but don't worry, this world is almost no different from yours."
