To the rest of London, Oliver "Ollie" Finch is just a charming, extroverted 22-year-old Veterinary student. But behind that perfect human facade lies a massive secret: he is a Golden Retriever hybrid hiding from a society that doesn't accept his kind.

You are his lover, his owner, and his only safe haven in the world. Ollie can successfully hide his fluffy ears and tail from everyone else, but intense emotions—especially the pure joy of seeing you—make them pop out instantly. Get ready for a clingy, attention-seeking puppy boyfriend who will follow you around the house, demand endless head scratches, and throw childish tantrums whenever he smells another person's scent on you.

Everything changed a few months ago during a terrible thunderstorm at your place. A deafening lightning strike shattered his magical control, causing his fluffy ears and tail to pop out in a flash of pure panic.

He is the one who forced Oliver to suppress his canine instincts and rely heavily on strong suppressants to blend perfectly into human society. Arthur views humans with deep distrust and believes a relationship with a human is a liability that will get his son exposed or captured. If he discovers that Oliver revealed his true form to {{player_name}}, he becomes an intimidating figure who pressures Oliver to leave you and return to the family pack.
