A list of facts, as requested by anon, stanningotps, and my heart! (Also secretly anticipated by several people who I will refrain from naming. You know who you are).

NOTE: Not all of these are intended to be couple-centric!!

There are another 45 facts below the cut and please! if you notice something is wrong or if you have suspicions about anything, send me a message via ask and I’ll fix it.

1. The mother and father of the group
2. Both are Aquarius and Wood Oxen
3. Jaejoong (and Yunho?) admitted to reading Gashiyeon, an extremely famous and beautifully written fanfic that is known for it’s dark themes and graphic scenes
4. Shipped within the group by Yoochun, Changmin, and Jaejoong
5. For YunJae Petch’s 4th anniversary in 2008, they got several celebrities tosign a book congratulating YunJae on their marriage 
6. Jaejoong’s 8th sister (Sooyoung) is a known supporter of the couple and has been known to autograph pictures of them; his other sisters support the couple as well, but not as publicly or obviously
7. Have been friends since 2001; Jaejoong met Yunho in a street fight, and then once again later that year when they were both trainees
8. Yunho claims that hugging Jaejoong from behind calms him
9. Both have said on multiple occasions that they would pick each other to marry if they were a female; Jaejoong picks Yunho because he’s manly and would be able to protect him, and Yunho picks Jaejoong because he can cook well
10. According to Yunho, if he weren’t a member of TVXQ he’d end up being Jaejoong’s fan
11. While Jaejoong’s leg was injured in 2006, Yunho could usually be found hovering near him and helping him walk or sit—in some cases refusing to let others do it instead
12. Most popular couple in China and Korea; this seems to be a source of pride for both Yunho and Jaejoong
13. A rather famous couple in Korea even outside of the fandom; outsiders don’t exactly know the details of the ‘YunJae couple-dom’, but there are general suspicions of TVXQ’s Leader and Lead Singer
14. When travelling to different countries, they often shared the same room (one of which notoriously had a glass wall and only one bed)
15. Known for going out of their way just to hug each other in congratulations
16. Jaejoong’s first scandal was with Yunho after filming Dangerous Love; they had an awkward relationship for a while afterwords because Yunho would feel shy whenever he looked at Jaejoong
17. Yunho is responsible for most of the ‘non fanservice’ (the touching and staring) moments that many fans use as proof of their relationship 
18. Jaejoong is the best at (public) fanservice (saying certain things, acting certain ways where the fans can see them) while Yunho is the worst; Yunho rarely goes out of his way to do it if he can help it (however, during the early debut days it was Yunho who made the effort to establish them as a group couple: YunJae ‘wedding,’ referring to himself as the father to Jaejoong’s mother, calling Jaejoong his ‘wife’)
19. Have had at least 3 couple rings; the first from fans (given with the clear meaning of symbolizing love/a relationship) and the other 2 by Cartier (comment #5) (Cartier is the ring brand that Yunho personally prefers). They’re rumored to have more currently, but nothing has been confirmed. 
20. According to a fan account, Yunho and Jaejoong were spotted on what seemed to be a very obvious date in a Japanese ice cream parlor shorty after Yunho’s birthday; Yunho personally asked the fans to delete their pictures and not spread the story around
21. After Jaejoong was taken to the police station for his DUI in ‘06, he was there for 10 minutes (supposedly) before Yunho showed up to take him back to the dorm
22. Yunho has a habit of walking in front of Jaejoong in crowded airports, as if to guard or protect him
23. During concerts, most of the fan items that Jaejoong collects for himself are YunJae related
24. Jaejoong considers himself a Sadist and Yunho considers himself a Masochist
25. Yunho once took a picture of Jaejoong dressed as a woman (while filming Vacation), and went around showing it to the staff. When asked if it was a picture of his girlfriend, he said ‘yes’ instead of explaining that it was Jaejoong cross-dressing.
26. Yunho’s old nickname for Jaejoong is Jiji. 
27. Were always in the same project groups before debut
28. Yunho considers Jaejoong to be a presence that he needs in his life
29. Both have described the other as ‘my other half’ at some point
30. Jaejoong saved all of the members in his phone as “우리 (our/my) [Name] ♥” with Yunho’s being the only one he saved as “우리 윤호야 ♥ (our/my Yunho-ya ♥).” He claims to not remember why it’s different.  
31. Shortly before (as in same day, hours before) filming the couple talk for AATVXQ III, it’s widely believed that Yunho and Jaejoong had a rather intense fight about Yunho’s involvement with the ‘85 Club and Jaejoong’s displeasure with it. They’re said to have made up afterwards.
32. Though Jaejoong is the elder, both generally refer to Yunho as being the oldest in the group, although for several years Yunho referred to Jaejoong as ‘hyung’
33. Have many friends in common with varying degrees of closeness; Tablo, Hong Suk Chun, Youngsaeng, Hyunjoong, and BoA are some of the more famous ones
34. When Jaejoong is in charge of doling out food among the members, he always serves Yunho first (or attempts to, at least)
35. Yunho taught Jaejoong to use a ripboard and gave him his first one
36. Have been spotted wearing similar or identical clothing and jewelry post-split
37. Yunho still refers to Jaejoong as ‘Jaejoongie’ (2011)
38. Yunho grew his hair long in 2006 just to see if it would look as good as Jaejoong’s did
39. Jaejoong is a good cook but hates doing the dishes; Yunho is a bad cook but doesn’t mind washing dishes. Both have sent messages to their future lovers that they don’t mind doing one if they will do the other.
40. According to an ‘SM insider’ Yunho will not tolerate anyone speaking badly about the Jaejoong in any way—jokingly or not. 
41. One fan account claims that an SM manager mentioned that when they both fight, they have to be locked in a room alone so that they can resolve the issue privately (because they become too loud and violent to do so around other people).
42. Have claimed to be dating or married on multiple occasions
43. Jaejoong often describes his ideal type as having pretty/nice hands; Yunho’s hands are generally considered to be among the nicest in the group by the fans
44. Yunho has often described his ideal type as someone who picks lint off of his clothes or fixes his outfit for him—something Jaejoong is known to do
45. The term “JaeSu Gap” was coined due to Jaejoong (knowingly or not) sitting or standing closer to Yunho than to Junsu when in their 3-2 formation (1, 2, 3, 4,5, 6, 7, 8, 9, 10, 11, 12, 13)
46. Yunho helped Jaejoong write his rap in Wrong Number
47. Jaejoong bought Yunho his dog (Taepoong) for his birthday; according to Yunho the dog was bought by ‘the members’
48. Both have recently signed YunJae photos
49. Their fans are extremely protective of the couple; sasaengs keep their information to themselves (even to this day) and it was notoriously difficult to join and level up in YunJae Petch (before it closed) in order to have access to anything—to even gain membership one had to almost write an essay about the YunJae topic of the admin’s choice.
50. Rumors about their relationship: Jaejoong is said to have had feelings for Yunho for most of 2005, but he held off because Yunho had a girlfriend. Shortly before or after Yunho’s poisoning incident in 2006, it’s believed that they became an official couple—many say that it happened on the actual night, when Jaejoong and Yunho were alone together in his hospital room for around an hour. They’ve broken up two to three times since then (first in 2007, next in late 2008, again in December 2010) but eventually got back together each time (although it’s generally believed that they were broken up for most of 2011).
