What is this yaoi manga called? Adults only?
It's split up into 3 sections. It's S&M-ish with the 'S' appearing in part A, B AND C.
SECTION A) a boy wants to buy an electric collar to stop his dog from barking in his new place. shop owner 'punishes' him by putting the collar around the boys neck and begins to 'train' him
SECTION B) high school boy gets punished for shoplifting.
SECTION C) boy wants to steal money from the shop lifter to make his younger brothers happy. he see's the two boys from previous sections getting 'punished' and helps them. in the end he gets caught and also becomes one of the owner's 'pets'
hope you can help :)
