@MyCatGinger@Saarebas It seems my powers of summary have been called on yet again. Let me know if I miss anything. Also, a LOT has happened, so forgive me if it seems fragmented or if I miss something important. I'll be omitting all minor interactions, so sorry if I don't mention many of the new guys.
Ok, so, Kyle and Nori were on their way to a happy relationship until Nori became the target of the serial killer, The Weatherman. Oliver, a private eye, took the case. Nori stayed the night at Kyle's for safety, and Oliver watched over Nori's apartment. The Weatherman struck, nearly burning Oliver to death, giving him amnesia, and making him look like Shishio from Ruroni Kenshin. While preparing to go to the ball at Amity's house (a famous international idol and Kyle's best friend), Nori decides to break up with Kyle for his own safety, and becomes Oliver's (now just "Dee") sidekick.
Yutaro has had a crush on Ryoki since the moment they met at Mochavine, and he finally asked her out on a date. they went to a fancy restaurant, kissed, and played strip poker. They agreed that they would try to look for each other at the ball, but would make a little game out of finding each other (Note: the ball is a black and white Masquerade. At midnight, masks come off, and you kiss the person closest to you). Yutaro decided to go straight to the bar and met Kyle. The two shared woes and liquor, until they were approached by Sabine... gonna need to flashback here...
A while back, Sabine met Zac at Club Lush. The two were grinding on each other hard core until Sabine decided she needed some... meth was it? She went into the VIP room, ODed, and Zac, who was chilling with Kyle and Nori, had to take her to the hospital. Yutaro, knowing exactly none of this, invites Sabine to have a seat next to Kyle to try to cheer his new buddy up However...
While Shou was at the ball, he saw a woman who looked like his deceased fiance, but it was really Amity in disguise. The two share an awesome dance, I believe they kissed, and Suzy snaps a photo of them. The yandere in Amity awakens and she goes up to Suzy,
demanding politely asking for the photo. Suzy refuses, however, preserving her professional integrity by insisting the photos go straight to the host of the ball. So, Amity believes that the best course of action is to taze Suzy. Kyle sees this, intercepts the assault in the nick of time, and carries Amity out of the hall. Yutaro is dumbfounded and now feels bad for inviting Sabine over only to have her potential dance partner run off, so he offers to dance with her before he goes looking for Ryoki.
Some other notable drama...
Nick. Poor poor Nick. In season one he was stood up by Nori. In season two he was rejected by Shizuka. And now he is expressing interest in the beautiful Kaga... who Nick doesn't know is a boy.
Alban, a single father, also appears to be establishing a relationship with Shizuka, though Shizuka's modesty and inability to accept that she's freakin' adorable is proving to be quite a stumbling block.
If you feel I have under-represented your character's importance, go ahead and add to this summary, but I think that's everything a newcomer needs to know.
