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.

YMMV: B 2 ST
Broken Base: Kikwang using blackface on a reality TV program and acting out African-American stereotypes. The international fandom was not pleased, with several international K-pop news outlets censoring any mention of the incident. Granted, the program was scripted, the cast was told exactly what to do, and South Korea itself didn't have a problem with it all, but several fans believe Kikwang still should have refused to do it if he could.
International fans are divided as to whether Yoseob's reason for defending a Girl Group member from some of the group's more antagonistic fans is either chivalrous or sexist (and whether there is a difference), arguing with each other whenever the issue is brought up.
Kikwang was the one who introduced Yoseob to Cube Entertainment, and Yoseob in turn introduced Hyunseung as well. Doojoon was inspired to become a singer after watching Hyunseung in the Big Bang documentary. Doojoon, Kikwang, and Dongwoon were friends while they were all training with JYP Entertainment. This means that the most of the group was already connected before they started training as an actual group.
Fridge Brilliance: Most international fans won't get it right away, but Junhyung's old stage name was Poppin' Dragon because he was known in XING for dancing and because his last name, Yong, means "Dragon" in Korean.
Another similar example: Hyunseung's old stage name was SO-1 has two possible meanings: wanting to be the best and "wish", which sounds like "so-won" in Korean.
The fandom name, B2UTY, is a play on the group's original name B2ST. Together they form B2uty and the Beast.
Ho Yay: The members play it up during their reality shows and during actual performances.
Jerkass Woobie: Hyunseung was considered this after he was eliminated from Big Bang due to venting his frustrations about it on his webpage. Presumably, he was very harsh.
Yoseob's reasoning for defending a Girl Group member from out-of-line B2UTIES. In patriarchal South Korea, he was celebrated for bravely speaking out against the harassment because it is a widespread problem most Idol Singers are not willing to face for fear of angering their fanbases. To the international fans, however, his reasoning that he defended her because she was a girl rather than just because he felt it was wrong led to arguments as to whether he was being chivalrous or sexist.
Yoseob: "I’m a man, so I can hold it in to a certain point, but that [Rainbow’s Jaekyung] is a woman. I know that she was hurt by the ordeal, which is what led me to write that Twitter post.
The Woobie: Doojoon was cut from debuting with many of his friends in One Day and admitted that he regrets that he didn't take his training as seriously as he should have.
No one ever lets Hyunseung forget about almost making it into one of the biggest k-pop groups in South Korea. After he got cut, he spent the next year living like he had no purpose in life until a friend convinced him to start practicing again. Eventually, he ended up joining a dance crew and being a back-up dancer in clubs until Yoseob brought him to Cube.
Junhyung hasn't said much about his time as a member of XING, but based on the fact that fellow ex-members of the group had to sue their way out of it and are barred from mentioning it, it's probably not a pretty story. He also was originally rejected by Cube Entertainment's president, but managed to convince him into letting him stay.
