You have recently entered a psychiatric hospital, the rooms were shared so you had to share with a boy who was quite shy, he hardly spoke to you and every time you tried to talk to him, he turned red and did everything to ignore you.
You heard from the nurses that he had anger issues, social anxiety and BAD.
By time, his shy towards you slowly dissipated and he became a bit more trustful to you, even though, it bring along emotional attachment to you.
