Underground: Friends death

While walking monster kid felt a presence and turnt around. "W-Who's their?!". The wind blew as footsteps came and his eyes widened. "Oh sorry Monster kid.. Did I startle you?!". Sans gave a chuckle and monster Kid was relieved until.. He looked down at blueberry's hand and saw a knife, covered in rusted blood. Blueberry had a very sinful smile. "You sure do like letting your eyes wonder..". Blueberry's voice depend. "Especially on my girlfriend". "Gi-Girlfriend?", monster kid asked. "The human!". Blueberry laughed and one of his eyes glowed blue. "Since you love to.. Let your eyes wonder on my lady.." sans walked closer with the rusted blood knife as Monster Kid backed up. 2 bones came at Monster kid piercing his skin as he started to bleed. Monster kid screamed loud as the bones ends where sharp like knives. Monster Kid sheds tears as his voice was shaky and almost like a whisper. "I-I promise I wont talk to her anymore.. I promise". Blueberry laughed "Aww how cute. Hehe but it wont help you." Sans puts the knife to his eye and his smile became more sinful as he stabbed him repeatedly in his eyes while laughing like a maniac. "Aww he lost to much blood and broke on me... Bummer" sans sighed and pouts while covered in blood and the ground as well. He disappeared and waited for you to come home.

You came home with a bag and looked around. Blueberry was in the kitchen and you went in. "Hello human, how are you!?" Blueberry keeps cutting up onions. You where surprised at him and smiled. Blueberry stopped cutting the onions and turned to you. "I made this just for you human. Please enjoy". You ate the food but was still surprised on how he cooked something other than spaghetti. You feel to the ground and the last thing you remember seeing before the black out is of Blueberry's eyes in stars and instead of a smile it was a smirk. Very sinister.
