These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Super Junior
Broken Base: Has happened several times within the fandom, such as after the original addition of Kyuhyun as the 13th member, the addition of Zhou Mi and Henry for Super Junior M, and the constant fights about how many members Super Junior actually has (thoughts range from 13, to 15, to 10, 8, 11 etc).
There's certain groups within the fandom called "13elieve" (supporting only 13 members of the group), those who support all 15... It's a very polarizing fandom.
Another example of this has been with the debut by Super Junior's record company of boy band EXO, which has 12 members - half of which promote in China. Comparisons are constantly drawn, with parts of the fandom quite bitter about the amount of money spent on EXO while Super Junior's last four music videos have been basically the same, set and costume-wise, and other parts of the fandom jumping ship to pay attention to EXO instead.
Crowning Moment of Heartwarming: There's a lot, like the members going out to beat up racists who picked on Hankyung. Basically, any candid moment baring the boys' experiences in their youth or while they're not in front of the camera invokes this trope.
Die for Our Ship: Considering there are A LOT of examples in fanfiction in general, let's mention the most common:
Zhoumi for Kyumin shippers. Most fics tend to portray him as the third wheel or a villain in favor of Kyuhyun and Sungmin as main couple. This, weird enough, rearely happens the other way with Qmi shippers, who just plain ignore Sungmin of the equation.
Speaking of Kyumin: Let's also add Ryeowook (mainly for the possibility of Kyuwook), and Sooyoung and Sunny both for Sungmin.
Fx Victoria for some reason is getting a lot of portrayals as First Love for Kyunhyun.
Jessica for any pair involving Donghae, due to past rumours of them being a couple in training days.
Either Kibum or Eunhyuk for Kihae or Eunhae shippers.
After the Twitter "accidental" photo post, a lot of fans, including Eunhae shippers, started harrasing IU for her photo with Eunhyuk. There were also some fanfiction out there, too.
Strangely averted with Sihan, Hanchul or Sichul, where either go straight to the romance or even ends up in Sihanchul.
Meta example: Just be a female celebrity and team up with any of the boys even for a TV challenge. You'll get harrased or be written as a bitch in a fanfiction by the shipper fanbase.
Ensemble Darkhorse: Ryeowook's role as the spastic student council vice-president in the band's affectionate parody movie "Attack on the Pin-Up Boys" was a fan favorite and actually won him both praise from movie critics and nominations for Best Supporting Actor and Best Comedic Performance at the Korean Movie Awards.
In a minor level, their manager Kim Junghoon, also has his own following as he's good looking and looks like the boys' big brother. He even was nicknamed "Prince Manager" and had his own fan signs.
Felony Misdemeanor: Except for Shindong who is happily engaged, whenever the other guys are spotted with a girl or are good friends with a girl celebrity, the fanbase of both sides flip out and the flames start all over the forums and fan-cafes.
"Funny Aneurysm" Moment: During the Explorers of the Human Body program, the members pranked Eunhyuk and Ryeowook to make them cry tears of genuine sadness. They did this by pretending to start a fight over Shindong leaving the group to pursue a hosting career. After the fiasco had ended, Kangin said "we must never let this happen in the future," "this" being the breakup of the group. Fast-forward to 2011—Kangin ended up taking early military service after his drunken assault, Han Geng sued their label and went back to China to start a solo career, and Kibum hasn't been seen anywhere since Sorry, Sorry.
Kangin has returned, however. And unlike most solo artists who have left their bands, Han Geng has not waved off the possibility of a reunion. The only problem lies with SM Entertainment.
Gag Penis: Yesung has become this in Memetic Mutation between female fans. It doesn't really help that his signature looks like one, if you look closely.
For the latinamerican fanbase, google "Yeyeconda", that's all the prove you need.
Eeteuk. What with the sexist comments, his need to always be in the spotlight, and the infamous blackface incident, he's been getting a lot of rage. At the same time, he does try hard to be a good leader, and a combination the band splintering, the incredibly hectic work schedule, falling sales, and the impending two years' national service that might erase everything he's worked so hard for has really taken a toll on him. When news of his incredibly depressing tweets and videos of him bawling his eyes out during Heechul's last stage came out, fan reaction could be summarised as: Come here so I can give you a hug, you fucking asshat!
Portmanteau Couple Name: In a group of thirteen to fifteen men with a possibility of 105 pairings (not even going into the threesomes), this is inevitable. Examples include Kangteuk, Hanchul, and Eunhae.
Shipping: The members are well aware of this, particularly Eeteuk+Kangin and Eunhyuk+Donghae, and insist on playing it up.
Heechul has admitted to reading fanfics about him. Specifically, Slash Fic of him and Han Geng, who he apparently can't look at the same after...
Eunhyuk enjoys KangTeuk fics, especially ones where they have children.
A fan wrote in a question to a radio station asking Yesung if he had ever read fanfics, and how he felt about them. His reply (translated): "I've read once. But why?! Why?! Why is it about the relationships between our members?...Why always me dating Ryeowookie?"
Ships That Pass In The Night: Another unusual couple in fandom, besides the Crack Pairs is "2jin", which stands for Jongjin and Sungjin, Yesung's an Sungmin's younger brothers. Helps fueling the shipping the fact that both are cute as well and seem to be good friends also. This is also subverted, since both of them knew each other from their brothers' family reunions.
Although Shindong's even been called out by Korean fans for acting like a moron on an awards show (going behind winner IU and making stupid faces even after someone tried to pull him back - twice◊!), and commenting that women should be skinny and take care of themselves.
There's also values dissonance on the part of the fandom - Shindong was revealed to have had plastic surgery, and pretty much the entire SJ fandom cooed over it - a far cry from how they treat female idols who admit to it! (To be fair, female k-pop idols have far more rigid standards than male.)
