At school, Hinata and the others are told to make an original board game for class, and the theme they choose is nothing other than "Mya-nee"! Miyako can't hide her anxiety when confronted with a board game designed to help her be less shy, but then she realizes it's a chance to get closer to Hana-chan. She gladly joins in, and what awaits her is...
It's been so long since 
I slept with Mya-nee!
Lange nicht mehr mit dir zusammen geschlafen!
¡Hacía mucho que no dormía contigo!
¡Hacía mucho que no dormía contigo!
Ça m’avait manqué,
de dormir avec toi !
È passato un sacco da quando ho dormito 
l'ultima volta con la sorellona Mya!
Faz tanto tempo que não
durmo com a Mya-nee!
Давно я не спала с тобой!
