link, please! its a yaoi manga. there was a chapter about the seme who brought the uke to his family introduced as a friend. then seme's sister dressed up the uke with frilly clothes. there was also a scene where the seme also introduced to the uke his fostered cat who stilll sleeps on his bed even he's no longer staying there. sorry for these vague clues (● ̄(エ) ̄●)
