The Special Chemical Reaction Between Angels and Demons

If an angel queen and a demon queen become classmates, what kind of chemical reaction will they have with each other? From elementary school to high school, every time I wanted to express my true feelings, I was forced to hold it back because of the special chemical reaction between the two of them. Even if one person is allowed to show preference, he is willing to be generous for the rest of his life. We can look back on the old years and grow old together with deep affection.
