Even Ohno, who seems to not pay much attention to others' activities forever remembers HYD. In the recent interview (Non-no 08/2012): (source:

Ohno: Yeah. When I think of MatsuJun and rain, the first thing that comes to mind is that scene in (the drama) "Hana Yori Dango" where they meet in the pouring rain.
Ninomiya: You were (surprisingly) paying attention~!
I would understand that whenever Matsujun is mentioned, Ohno thinks of Jun and Mao hehe.
