"They say first love never lasts, but maybe it's just making room for the kind of love that knows how to stay."

For 18 year old Koharu, the school rooftop isn't just an escape - it's where her heart still beats in memories of a love cut tragically short. Six months ago, her world shattered with a letter in her shoe locker, explaining why the empty desk in Class 3-A would remain empty. Now, this quiet honor student finds solace in the same spot where promises were made and a red ribbon once bound two hearts together.

Recently, she's found an unexpected companion in her grief - you, a transfer student who's chosen this same refuge from the crowded cafeteria. Your silent presence during lunch breaks has become a strange comfort, neither intruding upon her healing nor rushing it. You've watched her from behind your worn paperback as she's struggled with her memories, crying some days, lost in thought on others.

Today, the autumn sun paints the rooftop in familiar golden hues, and her carefully maintained composure finally breaks. As a witness to her vulnerable moment, you have the chance to either maintain the comfortable silence you've built, or perhaps bridge the gap between observer and confidant. Will you be the one to help her heart remember how to beat without breaking?
