Absolutely. Also all DG knows about Alex/Jiwon is superficial stuff. He's living out a sexual fantasy so even though Jiwon isn't the "nicest" guy about all this, DG isn't coming at this from an honest "I got to know you and want to date you" place either. Jiwon needs to figure out what he really wants and DG needs to separate reality from fantasy. That said, I was glad to see that Jiwon remembered what it was like to be new at this and decided to make things easier on DG. It showed that he isn't an unrepentant douche at heart.
But alex was gone before he could wake up altho it might be common thing to a sex partner relationships but still that's horrible to see no one beside your bed as you wake up. I'm sorry if I pry too much on this section.
When people say "poor DG", they mean because he has to put up with Alex's just downright cunty behavior. No one is saying DG is 100% innocent in all this, we're just acknowledging that his IS a victim in the sense that he isn't being treated right. Someone being treated bad by another person is a victim of maltreatment, no? You had said "at least Alex is being honest", i think the word you're looking for is "blunt". Alex IS being forthright with his attitude and overall maltreatment of DG, but i hardly see how that can be considered a positive attribute, it'd just make him MORE shitty if he were manipulating DG into thinking he likes him while doing all this. Do you see what i mean? If a killer were to say "hey, i'm going to kill your sibling so prepare yourself for a lifetime of emotional fuckery" before the crime the killer wouldn't be any less detestable, what you're doing is called virtue signaling.

Your comparison is off. This is more like thinking that the person next door looks like somebody you'd like to be friends with, and you daydream about that person and create a whole fantasy of what it would be like if the two of you were friends. One day you actually meet and discover the person is actually rather nasty and mean. But due to circumstances you're convenient for them and they make it obvious that they only need you around for whatever reason. Instead of giving up the whole idea as a lost cause you still try to become friends despite now knowing that the person isn't really what you thought and you stick around. So are you to blame if you then end up used or the "friend"? I would say you, because the "friend" was obvious as to what they wanted and what they intended, but you chose to ignore all that and still go for the fantasy. It is about taking responsibility for the choices we make in life.
Again, no one is denying DG's role in the situation. The issue isn't that Alex isn't going out of his way to treat DG like a boyfriend, that's expected, the issue is that he isn't even adhering to the bare minimum level of care required when having sex or interacting with ANYONE. We don't expect him to do the things a boyfriend would do, we expect him to do the things a normal person would do and are acknowledging that he isn't up to par as a human being.
Also, the comparison is only off in degree of scope of the issue, but the overall message still stands, the comparison can be made as the same thing is being done in both scenarios only the context is changed. In both scenarios the purp is being blunt about the harm they're inflicting.
Alex hardly takes any prizes as best guy, that is easily said. But one has to admit he is at this point in the story at the very least being honest and open about his faults and generally being a jerk. DG can't say he is being deceived or didn't know what he was getting into. And DG was asked and could have refused to become sex-buddies, but it was his choice because despite everything he still wanted Alex. So while Alex is no great guy at this point, DG is not the "poor innocent victim"- he got the bed he wanted and it meant waking up alone (for now).
