Wonwoo works at Shining Diamond Cafe, and Mingyu lives in a flat two stories above it. All Mingyu had to do was buy a latte to get the cafe's wifi password, and he's been using it in his apartment ever since. Meanwhile, Wonwoo's boss demanded that he catch the thief who's been stealing their wifi.  ... A tale about the most important things in life: coffee, love and wifi.  

What happens to Mingyu and Wonwoo after the end of That Stupid List?  Yes you have to have read That Stupid List for this to make any sense!!!

Junghan was slurping down chicken-flavored noodles when Mingyu started to fall for him. It was strange, because Mingyu had only ever fallen for girls before. Perhaps it was the noodles, and not Junghan, that Mingyu actually coveted.
