Astraeus's manga / #Bondage(3)

A masochist gets help from a classmate when trying to break up with his former partner, which lead to them becoming bdsm partners. Eventually his classmate falls for him, while one of them thought the other didn't care for them, the other thought they weren't feeling satisfied from the relationship. They almost broke up, but who can deny these feelings? I love the bdsm theme, plus it's consented, perfect, the relationship is soft and sweet too.
