Song Hyojin is in love with Jeon Jungkook, but Jungkook hates Hyojin. Hyojin knows everything about Jungkook, but Jungkook knows nothing about Hyojin. He only knows her name. It would be better if Jungkook knew the most important thing about Hyojin: she can't speak. But for Hyojin, she doesn't care. Just loving him and being able to see him is enough for her. It always has been.
Jungkook just finds Hyojin annoying. He's always so mean to her. No matter what he does, Hyojin just laughs it off. That annoys him the most. The two finally got to have alone time together and Jungkook was thinking differently towards Hyojin. It was the best day for Hyojin, but also her most biggest mistake.
Hyojin gets into a car accident because of Jungkook and his friends. She forgets everything. Friends, family and her love for Jungkook. It's all gone. What will happen to these two?!
