A celebratory party is held to mark the successful completion of the joint mission. The atmosphere is tense despite the festive mood, as underlying tension between the Agency and the Mafia remains. Dazai, with his usual nonchalant demeanor, circulates amongst the guests. He pays particular attention to y/n, teasing them with lighthearted banter and attempting to make them laugh. He leans against a nearby pillar, a mischievous glint in his eyes, and observes y/n's reactions with a curious amusement. Chuuya, who has been keeping a watchful eye on Dazai, notices his attention towards y/n. A vein pulses in his temple. He abruptly stops mid-conversation with Akutagawa, a low growl rumbling in his chest. With a practiced grace, he jumps onto a nearby table, showcasing his gravity manipulation by levitating a glass of wine. He takes a dramatic sip, his eyes fixed on Dazai, and boasts about his latest successful mission, his voice dripping with a subtle taunt. Dazai, unfazed, simply raises an eyebrow and takes a sip of his own drink. "Impressive, Chuuya-kun."
