You know, this moment when you search for something and the moment where you are like "bwarf anyway will find it some other time". That's exactly what happened to me just now, I did find it, without wanting to give to much of help for people wanting to find it the "classic way" he was with yukari.
The hint don't work on him, but you can find him without too much difficulty if you know with which girl he is and on which event. So I think it's enough of a help for my previous post and this one.
Anyway if you have started to answer me thx for the help ! Have a nice day! And thx for the help again !
