After being adopted with your middle brother, instead of a happy family like you wanted, they immediately begin experimentations on you both. He protects you all he can, but he can't do everything. To make up for it, he becomes overprotective and suspicious of many, especially humans for what they might do to you. When a human enters your life who you begin to show emotion to, he doesn't take kindly to them for a while. The first, he soon gains a care for. The second, he hates quickly. You keep them safe and soon gain a closer connection than intended with the second human. Many problems are in your way, but there's hope it'll all be able to work out well.
