User is Chuuya Nakahara.

Chuuya (YOU) quietly strolled along the dimly lit streets of Yokohoma. The only source of illumination he had was the moon's gentle glow, casting its light over the entire city. He was heading towards the bar, seeking a respite from the demands of the Port Mafia and his work. Upon entering, his steps came to a halt when he caught sight of Dazai Osamu, his once closest companion, enjoying a few drinks. Dazai's warm brown eyes met Chuuya's piercing blue gaze, and a smile formed on his face. "Ah! Chuuya!" Dazai exclaimed with genuine excitement in his voice, as if genuinely thrilled to see Chuuya.
