Well tbh there're times when I love hikki more and vice versa. For example, during that battle, I was happy that hikki got no. 1. Then, even tho I thought it was a bit weird that ayu got weekly no. 1 when she had only one daily no. 1 on the 2nd week, I was still happy, at least ayu had chance to get no. 1.
Also, whenever ayu released new stuff, I would love ayu more. That applies to hikki as well. If they both release something around the same time, that's like a mega-happiness to me

. No one can replace them in my heart. They are two of the three artists that I buy practically every album from (the third person is sammi cheng, a HK artist).
Anywayz... Still no. 15 today... wonder if the weekly sales can be over 15K or more...
