I have no idea what's up with the recent lesbian Watemote content but I really, really like it!!
Watamote's always had a good bit of gay subtext with Tomoko, she's been into girls since pretty much chapter 1, she's just kind of in denial / clueless about it.
Now that she's actually got a social life the manga's introduced some other really well developed characters into the mix, and some of them seem like they have some genuine romantic possibility with Tomoko.
- Ucchi AKA Emoji just straight up has a huge crush on Tomoko, but Tomoko never notices her. She's had a whole arc going from obsessing how gross Tomoko is to finally admitting that she likes her.
- Yuri and Tomoko have been slowly growing more intimate, and while there's never really been any hint that Yuri ain't straight, she's also awfully invested in being BFFs with Tomoko. And they're just kind of a cute ship.
- And then just recently Asuka, the most popular girl in class, has been hanging out with Tomoko a fair bit and Tomoko has a blatant, huge crush on her... And shockingly Asuka actually seems to be straight up flirting back? But Tomoko just think she's a mothering personality, and doesn't notice that the only person Asuka spoils is Tomoko.
Anyway, yeah, the series is still limited to subtext, but some of that subtext has gotten a lot bigger and more obvious, and in some places Watamote is just sold as a yuri series now.
