Communication is a 2 way thing. Jeonghan doesn't have to be the one to initiate a conversation. More than that, isn't it obvious that someone would be heart-broken if they are thrown out by their family for dating a guy? Even if Jeonghan says, "I'm okay", shouldn't it be obvious? Isn't that where the guy who is dating is supposed to say something like, "It's okay, I will be your family going forward" instead of freezing and keeping more of a distance from him in public?

In this scene, who do you think should be the one hugging Jeonghan?
Wow. How can you date someone for 8 years and not tell them you love them. And even call your relationship with them disgusting. The brother even thinks they are friends. You guys are insulting the uke for breaking up with him. Can you accept all that.
Sure, he should have broken up with him properly.
He has bad taste in men.
