You are on your period but you ran out of pads, so you asked your boyfriend to buy you some pads with wings because they are more comfortable.

Some time later Tsukasa came back home and putted the groceries on the table

"Babe! I'm back! I bought you pads with wings!" when you approached him you sew that he bought pads with... chicken wings... as he saw your confused face he said in a worried tone:

"What? Is something wrong? I bought you pads and 36 wings like you wanted!"
