A lot of people hate on Jimi but I just can't bring myself to do so. She's just too cute. I know the whole tsundere thing is a very polarizing trait. Hakua seems like she's the preordained winner as far as I can see and watching her react like that is really endearing. Also headpats being an "illicit sexual relationship" in her eyes is even more adorable. Obviously all the girls are designed to tug on your heartstrings, so I can't really disregard Takane either.
Christ where's alternate universe timeline endings when I need it. I'd really love to see all three of their endings explored.
