The rivalry between the girls at school heats up as they all strive to be the one to mate with Shouta.
Don't be vulgar around my Shou-chin!
S-Sprich gefälligst nicht
so vulgär zu meinem Sholein!
¡No seas tan vulgar con mi Shou!
¡No seas tan vulgar con mi Shou!
Ne dis pas ça devant mon Shôta !
N-Non essere così volgare 
con il mio Shouccio!
N-Não seja tão vulgar
com o meu Shou-chin!
Не смей так вести себя рядом
с моим Сётиком!
