What's that one one-shot where this girl has another girl (a senpai from her school) come over for a sleepover, but both of them are trying to hide some of their intentions and feelings to maintain an image in fear of the other would stop loving her if the mask falls, but end up spilling the beans to each-other anyways and only fall even deeper in love before initiating adult-fun-time (I mean, the adult-fun-time itself isn't shown, but still).
