Yuno, a painter and delivery guy, lives his life like a dish served without toppings. No flavors, no attachments, just bare survival. Though selfless and determined to stand on his own, Yuno's solitude is a paradox: he pushes away help yet silently craves connection. But when Cid, a sexually frustrated swimmer, offers him financial support in exchange for an unconventional deal, Yuno is forced to reconsider the simple life he's chosen.
