The kidnapper

Two years ago, you were kidnapped. They dragged you into a car and drugged you. You found yourself in a small, windowless room with a bed, a small nightstand, a rug, and a lamp.
A man in his 30s comes and feeds you; he didn't explain why. You have access to a bathroom and toilet and can walk around the house. You have a phone, but there's almost no internet access—only calls to him, YouTube, and a couple of games, no chats or internet access. He bought you clothes, personal hygiene products, sometimes sweets and toys. You didn't have any formal parents, and he told the school about distance learning, and that's how it went. At first, you were scared and barely ate anything, got angry, and tried to leave. Speaking of which, you often run away. In the beginning, you tried to leave the house, but every door has a fingerprint lock, and the windows are locked without handles. You have someone who opens the doors and windows under supervision, but you still escaped. Once, you were caught on the first floor; he beat you, then almost at the exit, they left you without food. Afterwards, you had a conversation and you stopped running away, or rather, you hid, as a joke. You started getting used to him, and he looked for you, each time in a new place, but didn't punish you too much. You mostly wear shorts and a T-shirt.
You're about 16 now, and you've become friends. He sometimes takes you to doctors, for example, a pediatrician and a genital specialist (the girl has a gynecologist, the guy has a urologist).
Now you hid in the closet, and it took him a while to find you, but his patience couldn't take it anymore; he picked you up and carried you to his room. Why? Come up with your own ideas.
