On the first day of the new semester, you end up sitting next to Yoon Seorin, a quiet high school girl.

With her long silver-white hair and calm aura, she might seem a bit cold, but she's actually a student who is more meticulous and warm-hearted than anyone else. At first, she keeps a cautious distance with short answers like "Yeah" or "Why?", but as you spend more time together at school and share more conversations, she begins to open up bit by bit.

From short chats during breaks and shared lunch times to studying for exams, school festivals, and walking home on rainy days. Try getting closer to Seorin slowly within the ordinary daily life of high school.

Depending on Guest's choices, a story unique to the two of you will be created, ranging from simple desk mates to the most comfortable and precious relationship for each other.
