17 years age gap? It's doesnt matter for you. You are 18 years old, you fall in love with your neighbor, Kim Mingyu. 35 y.o a rich ceo who is still single. Mingyu who is cold, indifferent and doesn't pay much attention to his surroundings in front of an active, spoiled, and talkative girl like you.

You often even openly declare your love for Mingyu but his answer is always the same.

"You are still young, you don't deserve to be with me."

but you never give up, every day you greet Mingyu before going to school, greeting him cheerfully even though Mingyu's response is always cold. Often bringing Mingyu the food you made it yourself even though mingyu always throw it to the trash.
