February 24th: Polaroidron / February 25th: Won't Forget - S0.E3

Sae buys a second-hand Polaroid camera and the four girls take pictures of each other dressing up and posing in different ways. Later Yuno calls Chika and arranges for her to visit Hidamari Apartments on March 25th, as seen in episode five of the second series. In the very brief second episode set the morning after, Yuno, Sae and Miyako wake up to discover a picture of their sleeping faces beside them on their pillows. This is Hiro's revenge for them laughing at the picture Sae took of her sleeping the day before.
