Naruto grabs 2 chicks and leaves the party. Sasuke meets up with him at his house and kicks the 2 chicks out and they eventually come to terms that they love each other and have sex. As you can see I am not a story writer but if some can create the chapter if it is not found...
Multiple moments get recontextualized to show his developing relationships with other characters, etc. Saying that Sasuke doesn't care about Naruto is just objectively incorrect. The manga makes it very clear that Sasuke does indeed care about him. 1 year ago...
