Jeonghan has spent many years working at a café with his family.  He's loved working there so much, that when he became an adult, he opened up a shop of his own.  The café is named 'Warm-Milk Café". 

Joshua works at a normal everyday office building.  He clocks in at 9am and leaves at 5pm.  He lives alone: ten minutes away from his work.  Many times he would go to a bread shop for lunch.  Because the bread shop closed, he needed to find a new place to spend his thirty minute lunch break.  That's when he stumbled upon a cute little café.

Can an easy going café owner and a boring business worker attract each other? And when Jeonghan's ex boyfriend finds out about their love, what will happen?
