maybe the author can add another male character for him. I've seen gay & lesbian characters outside of yaoi/yuri manga.
Since it seems everyone is falling for Neji, the solution should be obvious. The government should pair Nisaki and Takasaki, then they'll move in as neighbors of Neji and Liliana. To the outside world, everything is as the government decided, and the four aren't penalized. Late at night, however, behind closed doors, they all share Neji! Hehe!
lol that would be different. I wouldnt mind that ending if they can set aside jealously. (●'◡'●)ﾉ
Nisaki poor thing you're in love with Neji ╥﹏╥
too bad this is not yaoi ┗( T﹏T )┛
