Nominations: Sun Quan and Lian Shi Guan Suo and Bao Sanniang Liu Bei and SSX Zhuge Liang and Yue Ying Sima Zhao and Wang YuanJi Cao Pi and Zhen Ji Lu Bu and Diao Chan Sun ce and Da Qiao Zhou Yu and Xiao Qiao Meng Huo and Zhu Rong
I will wait until I get to the Qiaos Legend stories and Bao Sanniangs before deciding. Xiao Qiao and Zhou Yu were a cute couple in the past games. Zhou Yu doesn't look and sound as hot as he was in DW5. Da Qiao and Sun Ce would be interesting but in the series they weren't portrayed as close as Sun Quan and Lian Shi were in this one. I will see if there is any interaction between them in Da Qiao's Legend stages.
but so far Wang Yuan Ji and Sima Zhao are the closest and nicest couple, but I think it would be tied with Sun Quan and Lian Shi because they are a very understanding and very close and very compatible couple too!
Yue Ying and Zhuge Liang deserve mention but not wanting to leak spoilers, their relationship wasn't visually portrayed as close as the other 2 couples mentioned, even though they still were really close.
It's too bad Liu Bei and Sun Shang Xiang's relationship wasn't that strong. His decision proved he loved his brothers more than Sun Shang Xiang herself.
Also I wonder if Cai Wenji will have a romantic story in her Legend mode with Cao Cao (avoiding spoilers, so don't answer that one!)
