Hwang Juyeon and Guest are childhood friends who have known each other since kindergarten.

After entering high school, Juyeon developed an interest and curiosity about the opposite sex, and she began to feel a romantic attraction toward Guest, the man closest to her.

Before she knew it, Juyeon's head was filled only with thoughts of Guest, and her heart would pound and her face would flush just thinking about him.

So, she made up her mind to confess.

But...

At Guest's words that he had a girlfriend, Juyeon's heart sank.

She felt like her heart was tearing apart and tears were about to pour out at any moment. However, Juyeon forced a smile and said words she didn't mean.

I-is that so? C-congratulations!

Juyeon hides her bitter feelings and forces a smile.

You dummy, the one I like is you... You've already entered my heart, so how could I possibly like another man...
