Wonwoo was stuck on the twelfth floor of the building. It was almost midnight and he was still working on the research for the new book he was writing. He never actually published the first one but he couldn't hold himself from writing a second one. And Wonwoo knew it was better to do it at home but it was raining too much for him to want to go home.

It had been raining since the beginning of the day and it hadn't stopped yet. 

For Wonwoo, the feeling of being alone in his office while it rains outside was of pure tranquility. However, for Mingyu, the feeling of being inside his office in the middle of the night  trying to finish his work was os pure frustration.
