They do get character development, I want to reread it fully!
Caste Heaven
Ch 11-14 is my favorite couple. Also appears in the ‘Behind the game’ in volume 3 (page 175), and in volume 6 (page 175). And also in the last chapter! (hinted at in graduation, and 10 years later in page 182) Volume 4 Side Story (Ch 175) has the buff bottom and the tall gloomy top. Volume 3 Side Story (Ch 147) and Volume 4 Behind the Game (Ch 199?) focus on the small x huge guy. Ch 15.7 has brief scenes of most couples.
Moon and Sun(Abe Akane)
Hilarious, love these two.
