She literally all through the game if you go against her talk about kill the mc to get her mother back and how only she can have sothis. I mean she burned a whole city full of people to kill the mc to get sothis back
Chapter 152 openly reveals that only Ucchi has true love feelings towards Tomoko, while others just want to be best(?) friends despite their so called yuri bait actions. Ucchi face here is just a face or pure maiden fallen in love!
Somewhat similar situation happens with Yuzu and Kaede in SakuraTrick, love through pain of loneliness and endless waiting and fear of being rejected.
^Excuse me but what. That whole shebang was literally the natural result of Emoji's bizarre stalker crush at an arm's length contra the harem proper that actually directly interacts with Tomoko like normally functioning human beings... -.-;
^^That seems like a pretty poor read of the other's characters, especially Asuka's. My point still stands though, Ucchi hasn't done a real effort for knowing the true Tomoko. Yes, Ucchi has issues on her own to work out but she needs to understand herself first, before hoping to aspire to make something meaningful with Tomoko.
As far as I can tell, (apart from being a gag character) Ucchi is only popular because of how strongly she comes off. If Yuri, Asuka, or even Nemo ever showed any kind of irrefutably romantic feelings for Tomoko, I bet the Ucchi shipping would drop dramatically.  ̄\_(ツ)_/ ̄
Also I'm disappointed this is the only fanart with both HotaAo (Callie x Marie) and IiHime (Marina x Pearl). There's also only one Pixiv set with both.
^ Saying that is implying Ucchi ship is popular when it's not even in the slightest. Ucchi ship is considered like the weakest one because of how the author always treat Ucchi like a joke character. And if you ask some persons, Asuka and Yuri will had already show romantic feelings, especially Asuka given how popularit is contrary to Ucchi.Anyway in the end, Tomoko will end with nobody because it's not a yuri so they will just endep up as a huge group of friends.
