Goddamn I love Ichika too much, she's my favourite by far, her chemistry with Fuutarou is easily the best and her snake moments only made her character arc even more fun and interesting to read. She needs to win.
Also wanted to say, Ichika and Itsuki are the only ones with whom it feels like Fuutarou really talks to normally as equals, Nino, Miku and Yotsuba really feel like his students first and friends second. And Itsuki is still not really in love with Fuutarou as far as we can see.
