I think you're projecting someone you know onto him, DG's not acting like that. He was just trying to make small talk because Alex leaves a lot of silences.
It's more the fact that Alex is making clear that he doesn't want to get to know him but he keeps trying to socialise. It's really uncomfortable when people do that. It's like when you're in a taxi and you're praying that the driver won't try to make small talk. But you may be right, maybe I'm projecting someone on to DG.
I totally get your example, but it's just that normally when you have that situation you're not also having sex with that person or shoving two cocks up their ass lol :') I feel like if u done that, you owe them at least a little bit of conversation and I mean *owe*
But yea I don't really like it when guys go all "nice guy" on me when I'm not feeling them either so I kinda get where you're coming from. I'd just never also sleep with someone who I felt that way about
A lot of people are saying Alex is dumb for not liking DG, but in real life you'd find someone like that really irritating. Guys who seem desperate to make clear that they care about you are often really off-putting. You gotta play it cool. DG is constantly like "omg hey sunbae how's it going what's up gimme your life story" - it's exhausting...
