Mayoke no Darling – Okuyama Puku

At the university’s badminton club’s freshmen welcome party, everyone is scared stiff when the scary-looking Tougo introduces himself. The fearless (or maybe just clueless) freshmen Haruka ends up sharing a taxi home with Tougo… and while everyone else trembles in fear before him, Haruka finds him handsome.

Mayoke no Darling: Akuma-sempai falls for airhead-kohai. Kohai discovers sempai’s true nature. Fluff-tastic fluff follows!   

Red String of Fate: Pugs bring two schoolmates together. Animal-hating Fuuta learns skinship from Takuya. Proceeds to fall in love with the dog and the human. Cute!
