Does no one else find it odd that Azumi (the male teacher):
1: Knows Isechi is in trouble
2: Knows where Fujimura is, or at least she's potentially close to Isechi
3: Asks her of all people to take care of Isechi (calling the parents might be more natural?)
My theory is he figured them out from the start and is a desperate shipper even spying on them to find an opportunity to push them together...
I hereby want to nominate Azumi for the official title of "lesbro".
And yes, Fujimura's friend is also cool, but "lessis" sounds kind of weird, so I leave it to others to find a good title for her.
