That is no reason for Bi to be unhappy about. GF of the day is just a routine so it matters not if the selection part was prearranged.
a lot of the other stuff he does in the concert are also part of the routine.. so whether it's about the GF of the day or not of course he wouldn't be happy if somebody else tells him what to do in his own concert.
when he had a concert in HK, the first night of the concert.. the GF of the day was a Korean girl... it was an honest mistake but still tho' I remember somebody here said when Bi found out, he wasn't too happy about it.. especially the non-Korean audience...
