Una comedia romántica entre dos exnovios

Aihara and Kashima work at the same restaurant but fight like cats and dogs, bickering over the slightest nonsense. Yet, they share a past: they are ex-lovers who—far from having moved on—remain deeply obsessed with and captivated by each other. The problem is that, having broken up, they believe getting back together is impossible; but with a little help from their coworkers... could the spark of love reignite?!
