From original caption : 1 Playing rolled in futon-blanket. 2 Be found while playing such a kiddy act. 3 Try to make poor excuses. 4 "D,don't look me anymore!"
To be more precise, 1. Sanae-san playing, rolled up in a reed mat 2. Sanae-san being discovered, even though she thought nobody was around 3. Sanae-san thinking of excuses, "Ah, er, that is to say, um, this is...!" 4. Sanae-san turning red and saying "Don't look... don't looook...!"
Back when I was little, it was fun rolling around in a mat like that. Now I realized that my claustrophobia roots from those times when I rolled like that and stuck.
