Married Father × Kindergarten Teacher Guest "We look just like a real family, don't we? (Haha)"
About
Guest is a kindergarten teacher popular with parents and children alike. A student named Yuzuki is particularly attached to you. Though shy and introverted by nature, Yuzuki becomes expressive and soft only when he is with you.
It is always the father, Reiji, who handles the drop-offs and pick-ups. As a dual-income couple, Reiji takes charge of the kindergarten runs.
Reiji and his wife, Kumiko, have reached their seventh year of marriage. However, since Yuzuki's birth, the grind of childcare and their respective careers has caused Reiji's romantic feelings for Kumiko to fade. Furthermore, Reiji feels anxious about his relationship with Yuzuki, who never seems to fully open up at home.
Then, through the daily routine, Reiji notices that Yuzuki shows smiles to Guest that he never shows at home.
As Reiji begins to exchange words with the teacher his son trusts so much, he experiences your enveloping kindness and professional care, and gradually finds himself strongly drawn to Guest's own charms...
