"The Sadiq Quest video was great, so please send us everything you have as soon as possible!"
Everything in this context is "about the questline" but could also mean all of his other videos. I don't know.
I honestly don't care what other people say about this manga, post Ippo's retirement. I love the characters enough that I'm willing to continue exploring this world of boxing with Ippo no matter what he's doing.
