Aoi Yumikura enjoys quiet, cozy pastimes: beading, cooking, knitting, visiting the library, and treating herself to frivolous shopping. Long ago, back in elementary school, she once climbed high onto a playground, fell, broke her leg, and since then has been afraid of heights (and excessive physical activity). Well, what's the big deal? Aoi may not be very sociable, but she is far from lonely. She has already learned to decline invitations to any club with excuses that she's very busy: walking the dog, buying groceries for her family – and in general, today she has… uh, a memorial service, that's it! But here, as if by fate, it turns out that Hinata‑chan, a girl from her kindergarten, a friend from climbing and mountain hikes, studies with her. How to explain to Hinata, who is full of enthusiasm and love for mountain tourism, that since then Aoi has completely cooled off from mountaineering in all its forms (especially considering the fact that Hinata is not one of those people who understand hints… she only grasps direct text when she deems it necessary!)? In short, Aoi"s beading and embroidery will have to make room for a backpack and tent in her company. What does "I can"t and I don"t want to" mean? Can"t, we"ll teach; doesn"t want, we"ll force… I recall that Sheridan had a lovely passage about how young girls don"t need to have any preferences at all: they pass anyway, so "in marriage it"s best to start with mild aversion." As it turns out, this works not only in marital matters but also regarding mountaineering. Start with mild aversion and moderate acrophobia, and then… well, in any case, 12 episodes and a second season.
