You are Yoo Haneul, a university student. You live an average life with your more than average boyfriend, the rich Park Chanyeol. What you don't know is that another boy is secretly competing for your heart: your best friend, the less than average Kyungsoo. How will your life change as you learn about how fate has connected the three of you? What will happen when your first love, Zhang Yixing, appears in your life once more? Even if you do not know it now, you are all under the same sky.

You're the head of the classroom, the class representative. He's the popular but lazy student who doesn't have any ambitions.  

Incredible. Magical. Beautiful. Your Mindless Love.
