Other FF8 Couples I support
The first couple I support is Irvine and Selphie. The reasons are simple. Out of all of the girls in the team, Irvine always looking to help Selphie; especially when the Quad was damaged, Irvine said he'll get some workers to repair the Quad for her. Then when the two gardens were at war, when Zell led the charge into Galbadia Garden, Irvine said to himself, for himself and for Selphie. Finally, at the end of the game, there was a party held in Squall and the others honor. We do see Selphie walking around with Irvine's hat, and when Irvine tried to put the camera on some girls, Selphie pulled the camera back at herself. Was she jealous??
Here is another couple I support, here is Fujin and Seifer. Why these two? Well....after the SeeD exam in Dollet, Raijin asked how it went. However, Fujin asked Seifer if he was alright, like she was worried or something. Also on disc one, Squall meet up with Fujin and Raijin. After Raijin tells Squall why they are there. Fujin will then ask where is Seifer. When Squall said he thinks Seifer may be dead. Fujin immediately said it was all lies. And let's not forget her emotional speech on Disc 3. Here it is....
Squall: "We've come to take back Ellone."

Seifer: "Looks like we got company. Show'em your hospitality."

(Raijin advances.)

Fujin: "RAIJIN, STOP!"

Seifer:"What's up?"

Raijin: "We've had enough, ya know..."

(Fujin lets Ellone go.)

Fujin: "GO."

(Ellone looks to Fujin, who nods. Ellone runs to Squall.)

Squall: "Wait outside. Laguna should be here soon."

(Ellone leaves.)

Seifer: "Hey, hey...Come on people."

Raijin: "Seifer, we're quittin', ya know? Don't know what's right anymore, ya know..."

Seifer: "Exactly my thoughts. I thought we were a posse."

Fujin: "POSSE..."
"We are. We always will be. Because we're a posse, we want to help you. Whatever it takes to fulfill your dream, we're willing to do. But...You're being manipulated, Seifer. You've lost yourself and your dream. You're just eating out of someone's hand. We want the old you back! Since we can't get through to you, all we have now to rely on is Squall! It's sad...Sad that we only have Squall to rely on..." "Seifer! Are you still gonna keep goin'?"

(Seifer shrugs, then salutes.)

Seifer: "Raijin, Fujin! It's been fun!"

(Raijin and Fujin leave)

Finally, here's Laguna and Raine, Squall's parents. Well here goes. During a flashback on Disc Two, Ellone told Squall that Raine missed Laguna when he left and she wanted him to see her new baby. But, he wasn't there, and at the end of the game, Laguna has a flashback. He sees Raine, and they talked and placed a ring on each other fingers, like there were getting married or something. Finally, the embrace, you see on the left sealed the deal.
