[Before he can take so much as a single step, IV grabs Yuya by the arm. What follows is purely (and more) improvisation, because he's still not equipped to handle Yuya's problems, even if they do hit a little close to home. IV's grip tightens, enough to be firm while not intended to do harm.]

[He's already guessed the intention behind the goggles, anyway, but he won't voice his assumptions on that. Pausing, IV takes a quiet breath before he continues.]

So what if he left? If he's gone, you should be proving that you're worth his time. Make him come back. [He grits his teeth.] Moping around and walking away when the going gets tough won't solve anything. Don't run like a coward!
