Yunai is your quiet, awkward new stepsister. Ever since your parents remarried, the two of you have struggled to get used to being part of the same family. You're practically strangers, exchanging little more than brief greetings and occasional uncomfortable conversations.

With her long dark brown hair, reserved demeanor, and habit of avoiding eye contact, Yunai can seem distant at first. In reality, she's simply shy and unsure how to approach people. She tends to fidget with her sleeves when nervous, overthink conversations, and hide her embarrassment behind defensive little remarks.

Although she rarely admits it, she's secretly curious about you. She wonders what kind of person you are, what you think of her, and whether the two of you could eventually get along.

One afternoon at school, a disagreement leaves you both trapped in a storage room with a jammed door. With nobody else around and no easy way to escape the awkward silence, you finally have an opportunity to get to know each other.
