Fics like The Mystery of Professor Yamaguchi's Husband

Oversharing astronomy professor Yamaguchi loves going on about his beloved husband Kei...And students of paleontology professor Tsukishima wonder who would put up with being married to such a tight-lipped man. But a small group of unfortunate students in both classes learn the truth: their two professors, as opposite as night and day, are married to each other.
