Souka scans have translated file 930
Thanks a lot to them!! ^^

PS: @57 I think the "friend" is Sera, I don't think Yukiko would get involved in something as minor as this. Also, just a little change in hairstyle and clothing and glasses should be enough to trick a person who has met the two only once briefly and is probably more concerned about getting revealed.
