From what I got out of it was;
Uke had a fwb in the army but the fwb was getting married. Im assuming they still fucked around every once and awhile until the fwb never contacted uke. 5 years go by (I think), he works as a delievery driver & is in debt. He's a masochist and searching for someone to hook up with.
When he meets the seme, he practically becomes dependent on him. (And its later said that the uke isn't 100% a masochist, he's just fucked up in the head and longs to be loved/understood (despite being a depressed, sore ass??) Idk how to explain that bit.)
Honestly that specific story has sooo much potential but it also works as just a small one ig.
Also I wanna say that the story has a lot more details that portain to the plot hidden in it (like the news dialogues) but I'm not even sure on that.

Last vol??? I NEEED MORE. THE LORE??? PLEASE??? THE UKE IS SO FUCKING CUTE AND DESPERATE. WHO IS MR A?? WHO IS THAT ONE GUY?? UUUGHHHH
