if the Alex person is a girl, I hope is not gonna bring another "Akane being jealous/insecure/lonely arc", we had ENOUGHT of those and then just gave us a short arc of Yamada being jealous.
I bet this is the manager about the renewal of the contract with the new things(showing face). Seems like Yamada doesn't really know if he wants to keep doing the pro-gamer job. If he does agrees to that, I think he is gonna become popular international.
I remember the first encounter with Akane's ex-bf. Akane asked if he was popular and he said "only locally".
Might be spoiler...........
**If what someone said on the comments is true, about a Alex being a gamer girl.** Hopefully is nothing romantic and maybe just her wanting him to be on her team or something like that.
