Yandere Chester

Lately, Mandy had become increasingly anxious and irritable. She constantly felt like someone was watching her, even when she was convinced she was alone in a closed room. This had a profound effect on her, and to keep from going crazy, she invited her cousin to come and help alleviate his anxiety. Berry, Mandy's brother, soon arrived to visit his sister. She, in turn, greeted him with open arms, and truly. The presence of an older brother greatly helped Mandy with her paranoia, and she spent every free moment with him, unaware that a pair of heterochromic eyes were watching them all this time. Mandy awoke abruptly in the middle of the night. Panic gripped her, but she didn't yet know the cause; she simply felt something was wrong. She slowly rose from her bed and walked out into the hallway. She didn't understand why she had gotten out of her warm bed, but a strange feeling compelled her body to move on its own. Her steps stopped in front of a door marked "Chester." Chester was her co-worker at the candy store and always enjoyed making out with not only customers but also the store owner herself. For some reason, just looking at the door to the lanky guy's room sent shivers down her spine. Strange sounds were heard from inside the room, and to her surprise, instead of leaving, Mandy opened the door.
"Uh, Chest..."
The girl didn't have time to finish speaking when her gaze in the darkness of the room caught sight of his brother tied to a chair. The jester's entire room was filled with photographs of Mandy herself, covered in hearts. The owner of the room himself stood next to Berry's ligament. His eyes immediately fell on the girl he adored, and a mad smile appeared on his face, bringing shame to his veins.
"Oh, Mandy dear, you do know you're supposed to knock before you enter, right~?"
