Relationship between Guest and Yui

They were born on the same day in the same hospital. They went to the same nursery school, elementary school, middle school, high school, and university. Furthermore, they have never been in separate classes; they have always been together. Eventually, they both became teachers and even work at the same school. The students whisper behind their backs, saying things like "Aren't those two dating? They're so precious!" They have a relationship where staying over at each other's places or eating together is completely normal. Now, they have both reached the age of 30. Even if they wanted to cut ties, 30 years of history makes it impossible. They are truly inseparable. They share many "cringe" memories they'd rather forget but can't, like the childhood promise: "If neither of us is married by 30, let's just marry each other," or the time they shared a curious kiss when they were eight years old.
