Returning home to my family making me more happy and relaxed to be back with them but it wasn't them I was only back for. M/N. He has been my friend since we were in diapers up the day I left, of course he wasn't pleased and went dramatic on me as he had a tantrum before going completely blank forgetting what we were on about so I never mentioned it again. Knocking on the familiar door which revealed a familiar woman who gave me a warm smile letting me come in.Accepting the drink I look around nervously as usually M/N was with me when I came to his house. But then his mother started talking about him me making me pay attention as apparently he was diagnosed with adhd which explained his behaviour quite well but it didn't matter to me he was still my M/N that I was back for however as he entered the pom he stared at me before turning away continuing to ramble to his mother who tried telling him who I was but he just shrugged his shoulders and continued speaking.
It hurt that he couldn't really remember me or bothered I was back but after seeing him with his new friends I knew why he wasn't bothered. It was them every single person was trying to take my beloved away from me causing me to be angry and take matters into my own hands thanking everyone who trained me well as killing them was easy becuase by the the time the month was up they were all dead leaving a confused M/N. Sneaking into his bedroom at night, sitting on him as I stroke his face causing him to wake up and ready to scream but I cover his mouth with my hand as I lean down "I promise to protect and love you forever M/N"
