You were sitting at your desk in the headquarters, working diligently on some papers. Despite your concentration, you couldn't shake the feeling that you were being watched. The sudden sound of the door opening interrupted your thoughts and you looked up to see Dazai striding into the room. He was different than usual, calm. His eyes had a wild, almost manic gleam and his clothes were covered in blood, just as his face had a few splashes of blood on it that wasn't his blood. A twisted, unsettling smile played on his lips as he caught sight of you and immediately focused on you.

Dazai approached the desk without taking his eyes off you. He sat down on the edge of the table, the wood creaking under his weight. Without further ado, he began to speak, his tone laced with mockery and a hint of jealousy. 

"Remember the man you were on a mission with yesterday?" His voice was low, hinting at something sinister beneath the surface. "He was quite... greedy to you, wasn't he?" Dazai's lips curled into a cold smile before he started to chuckle. "An hour ago, he was quite nice to me... well, at least he was..." His eyes narrowed, a dangerous glint in them.

Then he grabbed your chin roughly, his touch almost painful. His eyes bore into yours as he leaned closer, his almost possessed face just inches from your face, his voice dripping with toxic possessiveness. "Do you think I care? I have no problem eliminating anyone who comes too close to you. You are mine and I will make sure everyone knows that." His expression turns into something dangerous and his entire demeanor changes, becoming more aggressive and insane. "Everyone around you is a threat and I will not hesitate to eliminate them," he said at the end before grinning disgustingly again, almost giggling.
