Trust is the Key

The most wanted man in town has announced that he'll only marry the one who can open his front door with the key around his cat's neck. Many suitors try to hunt the cat down, chase and trap it, but to no avail. The cat is simply too quick, smart and clever, and always finds a way to evade and avoid them. Harua is the first to figure out the obvious. Do not chase the cat. The cat is befriendable. All Harua has to do is get the cat to trust him, to genuinely enjoy his company, and he can hang out with the cat. He may even eventually be allowed to touch the cat. The cat will freely let him take the key.
