Kyle never opened up about his issues or trauma. He could be cold to you or hug you sometimes and then pull away and go in his room

One night he got hurt in the gym so you offered to massage his arm. He usually never took his shirt off because he was uncomfortable but he did. His torsos was covered in scars and bruises. Then he looked at you, sad and you took off your shirt too so he doesn't feel uncomfortable and you had a talk with him. After that day he was very clingy with you.
