Celeste's manga / #detective/police(2)

[ Detective, Obsession, Revenge ] So it was all supposed to be a "revenge" plan, but he never succeeded because his infatuation became love and even worse it became obsession. He even became his stalker (lol) So the dad is actually gay, he's in love with his childhood friend but they didn't work so he hated the idea of homosexuality and became homophobic. Then he found out that his son is gay so he lost his shit and became the psychotic person he is? Understandable, have a great day.

I can't remember anything except the sizzling smut. Old has a praising and being watched kink, the seme is his follower.
