Who should Mai be with?

I'm not sure who my oc Mai should be with. It is either Duncan または Tyler from tdi. Heres some things about Mai...

She has long ginger hair that goes down to her waste and she is short.
She is based off me so she is a strong girl but she has her moments when she is weak.
She is from Wales like me, and her name is welsh for May.
She can play the violin and she plays Rugby.
Her お気に入り TV 表示する is glee/グリー just like me.
And she finds it hard to stand up to the mean 人気 girls.

So who should be with Duncan または Tyler, and tell me why あなた chose them.
