In chapter 9 Miyako buys a pair of panties as a gift for Reika. She uses it as a kind of emotional blackmail* it's a gift from a friend, so you'll wear it, right? to get Reika to wear them. It backfires the next day, when Reika buys a really skimpy thongs as a gift for Miyako, using the very same reasoning.
Reika throws a melodramatic fit when she finds out, it's Miyako's birthday and she didn't get her any present. She throws herself on the floor, toppling her chair and desk in the process.
Reika staring at Miyako like crazy, when the latter unbuttons her nightgown, to measure her temperature.
Moe: While the art style of this manga is cute in general, Reika gets extra points whenever she' overcome with joy, sadness, worry or any other emotion except lust. Suddenly she becomes so naive.
