I can confirm some of the negativity towards Jacob. After Episode 10, he dropped a little in my eyes. Previously, he looked like a talented artist and a nice guy, a little cowardly, but this cowardice was justified when you are in a house full of jocks and you just don’t want to run into trouble.
But dude, you’re not trying to get into your friend’s ex’s panties, even more, come up and ask MC “can I hit on her?” It's just weird.
In real life, messing with your friend's ex is a quick way to complicate your relationship (imagine you're hanging out with a friend and bumping into your ex all the time) or even worse - becoming enemies.
