I honestly found this pretty realistic when you're dating as adults, where I'm from (25+). Especially with dating apps. Things start off kind of casual. It's kinda like when you go from "seeing stage" with more than one person to "seeing & sex stage" and "exclusive stage" where you go on dates with one person but not yet "boyfriend/girlfriend" stage. As your relationship develops, it doesn't really need a label before you become "official". It's kinda exhausting but it's realistic in modern dating.
