This is old news though. Matsuura talked about this anecdote already in Utaban a long, long time ago. Don't remember how long, but at least 10+ years ago, probably close to 15 than 10.
Suppose it's Goto's turn to bring it up and it goes around a bit again. BTW Matsuura also did this whole "I don't like you" routine with Abe as well according to that Utaban appearance.
