Theme song to that nightmare and the rest of his life: "Darkness, imprisoning me, I cannot see, absolute horror"
It seems like our boy is just fated to never have a normal relationship. First, he's used as a plaything, then he's become a pseudo-guardian while unconsciously repressing his feelings, going so far that refuses to start a relationship with a coworker his age.
Face it boys, he's on route to the bad end.
