I'm actually really angry at people saying that Kitty being into girls is unecessary because we kinda all agree that Minho will be the endgame and like... No it's not? Kitty is a great bi rep in my opinion. She had important romances with both a girl and a (two kinda) boys.
People say she was shown as "boys crazy" and first of all, no she wasn't? She really loves romance, as we see it in All the Boys I've Loved Before but that's all and she only had one boyfriend, the guy from season 1 (Dae I think but I'm not sure). And you can be bi and have a preference, that doesn't make you less bi. You can be bi without having ever date, or having only date one gender.
It's her sexuality, part of her identity. Even if it wasn't a whole storyline, it wouldn't be unecessary, but there it's like, a huge part of the series. Her feelings for Yuri are important. Her ending up with Minho will never change the fact that she's bi and it's cool to have this kinda rep. She can be in a "straight" relationship while being bi.
We know the huge biphobia bi girls dating men face, even within the community. People either say they're straight and faking it for attention, or that they're lesbians and in denial. Both is harmful. Straight boys sometimes date bi girls while having prejudices (like fetishizing them) and some lesbians refuse to date them because they "will obviously choose a boy over them". Bi people in general are also often seen as huge cheaters.
Bi rep is great and important. Especially bi girls rep and for teenagers. XO Kitty did a great job at making the relationship with Yuri really as great as with other characters, I didn't feel like it was thrown in to "bait" people: they have chemistry, screentime, a great storyline, development and super cute scenes.
(However, I think there is cheating involved in season 2 which suck but I haven't watch it yet so... Anyway not my point and as long as Kitty isn't the one who cheated we're out of bi stereotypes)
( Also, more personally, as a mixed and bi person, I do like seeing a mixed character who happend to be bi. Stuck in the "not quite this, not quite that" who's even more strong when you're white-passing/in a straight relationship. It's not because I grew up away from my mother's country that I'm less mixed, it's not because I'm dating someone from the opposite gender that I'm less bi. No one gets to tell me about stuff I happen to be born like and that are parts of my identity. It shaped me into who I am today for many different reasons.)
