Maybe, after the lecture from Himekawa. Otomore hasn't been subtle.
Considering we know he has noticed Osanai's feelings well before Himekawa's lecture rather than not notice more like his not really sure how to go about it for Otomore.
The way I see it, it looks like this.
Kinjyou is the one he admires and desires to be with but has no clue how to go about it due to the whole Otaku thing.
Himekawa the angry part of the fandom
Osanai girl he knows that likes him and is also the first person to become his friend because they wanted to which may have resulted in him being subconsciously terrified with the possible chance of losing her friendship if any relationship he pursues with her doesn't work out.
Otomore the OCP of the setting because we really need to know why she likes him so much as to blatantly confess her love in the form of song.
We already know that we can rule out the whole not noticing thing with Otaku here because it turns out that his surprisingly perceptive to said feeling's.
His just not really sure how to go about it...I just remembered his a fighting game Otaku based on what we've seen so far.
Not a general Otaku that's super into gal games and everything geeky so his hesitance and lack of clear direction to go with kinda makes sense abit now.
......I hope you can fulfill it!......Yeah
Th... Thanks.We didn't really talk much after that, even as we made our way home...
That day, I couldn't get her face out of my head
