So in this chapter Hata really just said: Oh you thought i was going nowhere with the latest chapters? Here's a spoiler about the real stuff. I want to make fillers not plot! Let me do my fillers!!
@thyfucketh um dunno abt the #1 heros brother backstory, but if you actually recall from previous chapters the little kid Morie is the 5th member of MCs ex party who is very attached to him and hasnt been properly introduced yet up to this point.
It's world building.
Aaand just about time to choke on his drink. And his words too

@Saury says what tho? he's not allowed to touch the subject... That's why he's scared of losing even the contract relationship by being honest
And chizuru (and agency) is the one who drew that boundary so she has more power...
