Présentation

On Christmas Eve night, college student Masuda met Kurihara, a guy bawling his eyes out at the convenience store where he worked part-time. Even though it was their first time meeting, he got stuck with his whining about being dumped right before Christmas, a real hassle. But when he learned he'd been looking forward to the date, he couldn't just leave him hanging... "Should I go in place of your girlfriend...?" Before he knew it, he'd offered to be a stand-in, and they ended up going on the date!? The next day, at the meeting spot, stood an intelligent-looking, sparkling Kurihara, a complete stranger compared to the crybaby from yesterdayーー!? Tearful, handsome puppy-like guy × apathetic but actually kind-hearted guy. A love story where he gets charmed! (Source: East Press, translated)
