@givemersspls: To my understanding, the not interfering refers to trying to get those two into romantic relation.
They obviously have that "yup, they're totally going to get married" chemistry already, but both seem oblivious to love.
Akai wanted to stick around and enjoy this slow bloom (and very comedic) love.
Sakaki on the other hand, think they should just get together and pushed for it.
Which is why Akai confronted him a few chapters earlier, she didn't want their relations to be rushed, and want the two to get together naturally even if it might be harder than getting Pandas to procreate.
