Was this a red flag?

my boyfriend watches netflix on his ps5. i was over at his house while he was watching netflix and i asked who's account was he using. he said it was his and i grabbed his controller and tried to look at the profile. as i was going to look at the account name he quickly changes it and says its not his but some family member and tries fighting me for the controller. i never got to see whos account it was cause i couldnt get to the menu but at that point he had already took the controller away from me. i know this is a light issue but his reaction to me checking whos account it was scared me
