Hi Anon! So, here we go: 

• Touka

Starting by the easiest, yes, obviously she does (just like him) and there are so many hints that I don’t think it’s very necessary for me to expand on this. xD 

It’s something they just haven’t told to each other out loud yet, but I think it might happen when the Dragoneki crisis finally is solved (or in order to solve it, we’ll know soon enough). :))

By the way, she has yet to call him Ken too, even though they’re married, but it’s a romantic development that will happen as well at some point!

• Hinami

Not in my opinion! I think Hina loves both Touka and Kaneki immensely, but just not in a romantic way, and the whole point of ch142 was to focus on her being mistaken when thinking that she was not good enough to be by their side.

She felt responsible for triggering what she thinks was Kaneki changing when the case with her mother happened & she felt “jealous” of Touka (careful tho, the word used in Japanese has a positive connotation as explained here), because she was striving to become as strong and reliable as she sees Touka to be. 

However, as explained in this great meta by @ayahinas​, ch142 was just yet another stone used to build up to more character development for Hina, which is something that I, too, understood as leading towards a likely romantic relationship with Ayato.

There was never any romantic longing for Kaneki in Hina’s character for me, rather he’s her family (her onii-chan). 🙂

• Eto

Nope, at least for me! If Eto ever held romantic feelings for anyone, I suspect it was probably Arima (even though Tatara was also longing for her ;_;) but I’m not an expert on this specific subject. x) 

In my opinion,

Eto was like yet another “mother figure” for Kaneki, which is a role she took upon herself too and which is why she said:

because with Arima, she ended “giving birth” to the next OEK. So, nope!

• Rize

Um, actually, Rize (as in the real girl, not the personification of Kaneki’s mind) probably doesn’t even remember who Kaneki is (I mean he was just this meal that ended up destroying her whole life),

so not at all.

• Mutsuki

Against, it’s just my opinion, but yep I definitely think  that Mucchan totally was obsessed and in love with Sasaki (not Kaneki though, just to precise, because it makes a notable difference since Sasaki is just one part of Kaneki). 

I explained why I thought so before here and here, so please check these posts for more details!

• Tsukiyama

It starts getting complicated. xD So to make things simple, let’s just say that I think it’s definitely possible that Tsukiyama felt something like romantic love for Kaneki at some point, but it’s not something that has to be as clear as day for everyone, including Tsukiyama himself.

Whether Tsukiyama ever felt romantic love for Kaneki or not though, for me, ever since he realized a while ago that these possible romantic feelings always were going to be unrequited, I think…

it changed in favor of a love that’s not romantic anymore. 

Tsukiyama only acted possessive & jealous with Kaneki back when he considered him to be a top class meal. After that, it became genuine concern over bringing Haise back to who he used to be, because Tsukiyama realized that he really cared about Kaneki as a person…

but still, never once after the Anteiku raid arc did Tsukiyama show any animosity towards Kaneki getting closer to Touka (look at how happy he was to organize their wedding ceremony or how much he already loves their future baby), which is why I can understand people saying it doesn’t have to have been romantic.

Best meta on the subject by @dreamofcentipedes :)) They explain way better than me for Tsukiyama!

And finally…

• Hide

Just like for Tsukiyama, I can understand why people have opposite takes on what Hide said to Amon…

…and I don’t mind whether Hide meant that his feelings are romantic or not.

The only thing bothering me (so to speak) is why we never had any clear hint of that (unlike with Touka, Mutsuki or even with Tsukiyama) before his words of ch148, if he meant for that confession to be taken in a romantic way, especially since he’s the one who’s known Kaneki for the longest time. 

Obviously Hidekane fans won’t agree on that, but that’s why I can understand some people seeing Hide’s confession as being similar to Eto’s, except that Hide’s link to Kaneki is meaningful in a completely different way. 

So I’m just undecided. On the one hand, the absence of previous hints makes me think it’s possibly platonic, but on the other hand, if it really is romantic, then I have no problem with that and I’m happy that Hide seems to be taking so well Kaneki falling in love with another person. :))

There you go, I hope it helps! Have a nice day Anon! ^_^
