Seo An is at some fancy event with CEOs and other important people to make connections. If you remember from earlier chapters, he’s been out of the spotlight for a while because of the PTSD he has from his abusive father — which is why he looks uncomfortable when his dad grabs his arm.
Also, I don’t know if you remember, but earlier on there was that scene where they played a trick on the pizza delivery guy and invited him to one of their get-togethers. By ‘they’ I mean the rich kids and heirs that Seo An knows, since all the sons and daughters of powerful families hang out in the same circles.
I don’t remember every detail, but when the delivery guy (Woowon) showed up, they were clearly trying to mess with him and humiliate him. Seo An got super pissed, yelled at them, and dragged Woowon outside because he didn’t want him to be a part of their cruel game.
Apparently, someone at that get-together secretly filmed them together, which is a big deal because if that video ever got out, it could cause a huge scandal — especially since Seo An’s dad is crazy and abusive.
As for the guy who is groveling at Seo An’s feet, I don’t remember why Seo An hates him or what that guy did but I’m sure he f*kd up somehow which is why he’s trying to get into his good graces. Maybe someone else knows.
Someone else explained this better in the comments below, but this is what I remember! Hope that helps!

That's very put together. But I forgot about SEO an, like he was emotionally abused by his family I guess? Is that right? What else am I forgetting?
I think I remember he got caught up in some files misplacing or smth when he started working in his dad's company but I don't remember the people involved.
Also doesn't the guy who filmed it wanted to sleep with SEO an or smth but now apparently his sister gonna get set up with him. Whoa.

The only part I can really add on to is your first point about Seo An. Yeah, he was definitely emotionally abused by his father — who demanded absolute perfection and nothing less. I’m pretty sure there were hints of physical abuse too. The pressure and constant mistreatment got so bad that Seo An actually broke down and needed medical treatment for his mental health.
If you remember, there were several moments early in the story where his father completely dismissed his struggles and acted like his mental state wasn’t important at all. His dad’s attitude was very much a, “get over it” one. He also felt like mental health problems weren’t a big deal. Very much a “boomer” way of thinking. It wasn’t until Woowon showed up that Seo An slowly started to get better.
Please and thank you
