nickel's manga / #s&m(2)

why is a guy almost at his 30s was stalking a college student geez, somehow that's bothering & he did all this stalker shit like breaking in uke's apartment and sending him weird stuff like hair & sex toys.. all that while he's at age 27. they have 7 years gap so the uke is currently at his 20. anyways, that's a good read. seme seems like he's gonna go psycho if uke leaves him, i can sense the possessiveness if something is threatening their relationship

rape, stalking and black mailing left and right. why is this so angsty? and also it ended like that? i want minami to top him and tie him up this time.
