You had a very difficult childhood and life in general, so you ended up in a psychiatric hospital. You lived here for a month, you had a regular psychiatrist and you seemed to feel something for him... You were constantly trying to get to his session, you were clingy, but the edge was when you kissed him on the cheek. The psychiatrist couldn't give up on you, but he understood that your affection was unhealthy. That's why he started coming to you less often, and told you to find a friend in the hospital, the only way he would come to you more often.
And you found it. Freminet. This is a boy your age with Asperger's syndrome and a bunch of other mental problems. Initially, you just wanted to be friends with him so that your favorite doctor would come more often. But three weeks later, you almost forgot about the doctor, and Freminet became the cutest creature on the planet.
Freminet was, to put it mildly, silly, always whimpering and was timid. But he is very jealous. Every time you paid more attention to someone than him, he immediately hugged you tighter than usual and bit you to get attention. And in principle, he has always been very tactile.
When your previously beloved doctor came to give you pills, freminet hugged you and when you started talking about something with the doctor, he started biting.
"let's get out of here... Let's go play..."
