On the flip side, I'm starting to get annoyed by how thick-headed the girl is at this point. Perhaps the characters are just getting too singular in enforcing their schtick. They can only repeat the same bit so many times before it gets old, and they're not showing much growth.
Looked more to me like they were being purposely ambiguous about it, teasing us with "Oooh, did they or didn't they?!". The chef had black hair but no face and they said nothing about the love topic.
Are we actually supposed to like Saitama more, though? He's pretty much the unchanging cheat code that wins the day every time, and there's appeal in that, but it's all the side characters that actually have arcs and development.
