1st couple- mating between a twin-tailed cat and a spider whew. The 2nd couple's smut WAS SO HOOOOOT I love megane/nerdy type senpais who are actually supa hot but the 3rd one was the most wholesome one uwu I wanted to see them all together with Gin-san in his 'human' form tho but really nice story. Deserves higher ratings than 9.0!!!
