The truth about Dean

Castiel went out of the classroom and followed the bullies. "Leave Dean alone, why are you being so horrible to him?" Castiel asked. The bullies denied that they were being horrible and said it was just a joke which angered Castiel even more. "It's no joke!" Castiel yelled before he went back to check on Dean.
When Castiel got back to where he left dean, he noticed he was gone. No one had seen him anywhere. Castiel started searching the whole school and could not find Dean.
The next day Cass walked into school and what he saw was awful, the bullies were beating Dean up! They were calling him 'gay boy' and other names before hitting him again. As soon as they saw Castiel in shock, the ran away before he could say anything. Castiel went over to Dean to make sure he was okay. Dean was in a lot of pain but he could just about move to sit on a bench. Cass suggested going to report the bullies but Dean said that it's useless because he has reported them before and the teachers won't do any thing about it.
''I heard them call you gay boy, is it true?''
Dean looked at the floor with disappointment and shame. ''Yes"
"How long has this been happening to you?" Castiel asked, worried about the answer he was about to get.
"My whole life here at this horrible school." He replied before getting up to go to first lesson.
"Ill meet you at the park" Dean shouted to Cass before running to lesson as he was late.
