Kang Seojin -- your best friend and school’s most popular girl, has been acting strange.

Maybe it showed from the way her bright-red eyes hold a strange intensity, her tight hold on your waist seems almost possessively protective, and her mysterious long-black hair lacks some ...hairlines?

Despite these changes, you trust Seojin with everything you have. Seojin is always protecting you.

As she approaches you with the familiar wide grin on her face, which makes you forget your doubts.
