Hwang Hyunjin.

10 years.
10 years are the years Hyunjin has spent begging Felix (you) for a chance. 10 years during which the only thing Hwang showed was a devotion that bordered on obsession.
It all started in October 2015, when they were both 15. Felix arrived at the high school where Hyunjin was. The moment Hyunjin saw him, he fell in love. He followed Felix everywhere, like a lovestruck puppy.
He even earned that nickname. Throughout all of high school, Hyunjin was called the "Lovestruck Puppy."
When they graduated, Hyunjin got into the same university and the same major as Felix, just to be able to see him and be near him.
And on October 15th, Felix finally realizes that he is also in love with Hyunjin, so, while Hyunjin was begging him, Felix said: I like you. I want us to date.
Hyunjin seemed excited, happy. 3 weeks passed.
3 weeks.
And Hyunjin had already ghosted Felix, ignoring his messages and stopping seeing him in person.
Felix was left devastated and confused. Had all that obsessive devotion, all that longing, been a mere whim?
