I'm afraid you don't get what I mean. Although you can spend time with your boyfriend/girlfriend everyday (and many people do), the problem is, here almost every couple spend their Christmas together. If you aren't with him/her on Christmas, people will doubt whether you two are really together. A little like Valentine's day. And nobody celebrate Christmas with family. For students who are single, they might do some activity with friends, but people over 40 years old seldom care Christmas since it's not a public holiday anyway. Not sure how it's like in Japan, but Christmas isn't a public holiday in Japan either.
It's the same in Japan. Where were you talking about, if not Japan? Just curious. I know it's like this in other places than Japan.
I'm from Taiwan. Though some people think Taiwan is somewhat similar to Japan and maybe that's part of the reason, but I think Christmas might automatically becomes like that in any non-Western country. Every other culture already has their own family reunion traditional holidays, so people don't add Christmas as another one.
Then I finally have time to read remaining recent shipping discussion...
I honestly do think that Rin and Shiemi are set in stone for one another. Nothing else would make sense to me, considering how far along the manga is now. They have feelings for each other (imo) and Shiemi made it clear that she saw Yukio as a friend. Before, she clearly had a crush on him, so much so that Oblivious Rin saw it too, but now? She may say out of her mouth that she sees Rin as a friend too, but her actions, to me, proves otherwise. And Rin has had feelings for Shiemi since they met.
As far as I can tell, both Rin and Yukio love Shiemi. As for Shiemi, since the beginning and until recently, she saw both Rin and Yukio as her friends. Recently she seems to be falling for Rin, but she rejected him because she doesn't feel ready and needs to sort out her feelings.
At the beginning of the manga, just like Rin, I was sure she had a crush on Yukio, but it seems we were both wrong.
IMO Shiemi obviously doesn't love either of them before volume 16, and it's clearly explained in the school festival arc. (She saw Yukio as some kind of idol when they met, but idol is different from love and she already knew Yukio isn't perfect in Kraken arc.)
Things changed a little after Rin's confession. She thinks she's not ready, and IMO it means she's not fall in love "yet". What chapter 73 and 82 showed us is, she cares less about romantic relation, but more about catching up with others and curing injury of others. Therefore I can't say she "had a crush" on Rin now.
Rin and Shiemi have actively helped each other move forward. The both make each other better and want to be better. They are each other's first friend. Rin also believes in Shiemi unconditionally. Even his concern over her decision to quit is more out of worry for her life. They're like a positive feedback loop of striving for more. The best part is, Rin and Shiemi do this unconsciously. They aren't aware that they gain any benefit from helping each other, but they do it anyways. That's why they're so sweet and compatible.
Yukio and Shiemi looked like that too, but it wasn't.
That's actually where I think YukiShi sometimes still seems more natural than RinShi. There's a fundamental problem in RinShi that Rin doesn't understand Shiemi. For example, Rin probably never aware Shiemi feels left behind. (Although it's the same that Shiemi doesn't really understand Yukio, but at least it seems improving)
Moreover, despite it seems like RinShi make each other better while YukiShi do not, and even Yukio might think so, I actually disagree. Shiemi's improvement is a combined effect of Rin, Yukio, and even Izumo. Rin regains confidence not only because Shiemi, but also because Izumo, Bon, and especially Koneko. When looking at RinShi alone, I actually feel their relation stuck
