But for the guy, he couldn't have done anything about it. Back then, they probably didn't allow gay, lesbian or bisexual relationships or marriages. So even thought he most likely had stronger feelings for the guy. Since he knows he can't do anything about his feelings for the guy he tried to keep them inside. Or he tells the guy, and the guy feels the same way, but someone finds out and then they can't see each other anymore.
In this line : Passing stranger! you do not know how longingly I look upon you,
I think that means that he's seen them before, and he might have developed feelings for a girl, or a guy.
