What is there to be sorry about, friend? Let's first remember, this is about the premise of a cartoon adapting a 4 panel comic.It's... about 99% not yuri, sadly. The heroine is kind of a accidental chick magnet, but it's only played for humor and doesn't go anywhere. Sorry....
I will argue the show in progress, an egg, as fragile and needing a further look under the lamp.
Meanwhile, Tomo's writer/author draws more eroge than just romance and compiled the story from its web template days mainly out of convenience and is likely to give up on it. Not what Tomo-chan needs.
I really think Tomo is a mascot for Q and that often in storytelling these days the Yuri part or pairing is like the aftermath of an assumed conclusion to that inquiry or introspection. Too deep for a 4 panel?
More pressure need instead be applied in the effort to let Yuri entertainment populate the tubes in a variety of surprising double takes and perhaps the anime version of Tomo could make that happen.
Fans often push for the conversations surrounding each new episode of any heteronormative to rather go that route.
I'll throw this last bit in, consideration about Tomo-chan's merits, for the protagonist does not espouse cluelessness only the chad counterpart. She reels and reacts around the same sex classmates a bit like Watamote's Tomoko. A look at either of these two perhaps better defines 21st century lesbianism. Or at the very least, how mangaka have come to interpret it.
And from the Tomo-chan mangaka's Twitter:
