Being jobless, Joshua just want people to accept him but the problem is that, no one is accepting him. One night after eating alone, he met Seungcheol his first love who actually saved him during their highschool time. Seungcheol is popular in the business industry, managing 3 restaurants and their family restaurant. Seungcheol asked Joshua if he can work for them during this Summer as their waiter, patissiere and singer, because he desperately wanted to be accepted he lied to Seungcheol but still accepted the offer.

Upon arriving at Seungcheol's hometown, Joshua met Seungcheol's two younger brothers: Jun, the cold hearted and hot headed head chef of Carats and Minghao, the flirty and playful youngest brother and studying culinary arts. 

Joshua thought that everything is alright until Jun went to him and confronted him about something, "You are just here for hyung right?" Jun made the decision not to let Joshua enter his kitchen and more or less make his stay this summer a very unforgettable one.

"During summer, people change, people fall in love, how about you?
Summer is a great time for people to fall in love, how about you fall in love?"
