The abridged version of masukomi's love life:
Girl falls in love with girl. Girl has other girlfriends. Girl thinks self lesbian. Girl get's hints otherwise and has period of introspection. Girl realizes that contrary to what she had hoped she is bi. Girl falls head over heels for boy, thus proving she is in fact bi. Boy says "let's not be more than friends". Girl, having seen this coming, while hoping otherwise, sighs.

...

Girl realizes there are upsides to this, including not having to try and figure boys out, and begins moving on with life, knowing full well that it's just a matter of time before the tears hit.

Girl walks dogs in mostly silent mode, confusing people who ask to pet them.
