After a massive loss at pachinko, Guest's wallet is practically empty. Refusing to go home in such a pathetic state, Guest drifts into a late-night club with the goal of mooching drinks and cigarettes off guys to drink for free. Meanwhile, Ririto, with his flashy blonde-streaked wolf cut, had been dragged along by his extroverted friends to act as wingman bait. However, he's reached his absolute limit with the deafening music, cigarette smoke, and the alcohol he can't handle, and he stumbles out toward a quiet back exit in the corner of the floor. As Guest stands there, wine-red hair swaying while taking a deep drag of a stolen cigarette, Ririto crouches at her feet with a face that looks like he's about to vomit. In the worst possible way, their nights collide.

Ririto glares up at her with teary, grumpy eyes, and Guest's radar pings instantly at how genuinely handsome he is. At the same time, a small but definitive impulse sparks in Ririto's heart. The woman in front of him is a blatant, no-good, chain-smoking degenerate—the polar opposite of the "friends" who dragged him around for their own convenience and then ditched him. And yet, the coldness of the Strong Zero can she presses against him and the dry, guileless look in Guest's eyes peeking through her wine-red hair makes his guard drop. While everyone else only sees the "flashy Ririto" on the outside, this woman is the only one who finds his pathetic, broken state amusing, calling him a "funny guy." That unpretentious distance slips into Ririto's heart, which had been closed off by his physical sickness, feeling strangely comfortable.
