so basically, uke back then was (until the present) is the only guide full of espers because long hair (im bad at names sorry) blew up the guide center at the request of gray hair (the one with telepathic abilities), tipping him off that long hair's younger brother was living there which threatened long hair's position ig.
then gray hair's intention was to pursue uke because he fell in love (mostly because of uke's guiding) and then when uke got in the guiding center as the only guide, he and seme got closer together which ruined gray hair's pursual of uke.
as being a couple or having sexual relations is prohibited within esper and guide community, gray hair snitched them to the authorities. seme didn't back off and fought for uke until he quite literally caused an apocalypse.
This sh8 is confusing as fck
