Isn't it very strongly implied that rival-chan is a lesbian? It seems like the artist is setting her up with office lady.

Both of those things can be reasonably inferred, yes.

"Very strongly implied that rival-chan is a lesbian"? How is it strongly implied? The morning after scene was a gag and this one isn't even inherently sexual.

Gag or not, Rival-chan's reaction in post #3946663 certainly isn't the reaction of someone who was displeased by the situation. There's truth in every joke.

I could very well be wrong -- we'll see if her flirting with the dude turns out to be nothing but a farce to get with office lady or something -- but I think you're looking too much into it (or perhaps not looking into it enough. post #3892279 Why would she feel threatened by the other rival if she's into office lady?). A lot of [western] english speaking people see gay stuff everywhere even where it isn't, because that's how our culture is now. Not so sure about Japan, where this kind of comedy is commonplace.

What she is, is a tease; she has been from the start.

...

To be fair, there is a decent amount of Japanese twitter users who are also getting homoerotic vibes from their interactions with each other, but that's just a portion out of many people who don't see any yuri behind it.

The author certainly teasingly acknowledged it though, but it's more of a Shrug of God atm than any confirmation.
