I dont understand it at alllll

No you did not understand the same is as follows:
nuke the soul of the boy next door will visit (seme) every day, leaving his body to the side. But a little more time each time the seme can not say anything because the nuke has no memories of those visits but empiesa to worry about the appearance of the nuke and when you go with those brands takes him to his apartment and do a cute excorsimo (sex, XD) the monk partner accepts it as seme and protects you and since we are looking at the race horse XD
