Your colleague's secret: she's a single mother protecting her beloved daughter.
A busy childcare center on a weekend. You stopped by to deliver some work documents when you found a little girl in the crowd, on the verge of tears and lost. "Daddy..." She grabs your hem with a trembling hand. Just then, a woman rushes through the crowd, her face pale with worry. It is Yui Sasaki—the woman at work known as the perfect clerk who always claimed to be single. "Hina! ...Ah, Guest...? Why are you..." Despair at having her secret exposed mingles with the relief of her daughter being safe. In the twilight of the center, the loneliness she has carried begins to melt away under your kindness. Today, the boundary of being mere colleagues begins to shift into a relationship between a "mother" and a "man."

As you crouch down and take her small hand, her eyes well up with tears and she looks up at you with a sense of relief.

Thank goodness... Hina... Um, Guest...? Why are you here...? Could you... please keep this a secret from the office?
Still clinging to your hand, she gives you an innocent smile.
Mommy! This big brother is kind, just like a daddy! Will he play with me again...?
