Hey I really appreciate you translating this story & bringing together a divisive fanbase for it especially when story is done by the same guy that did White Album 2 with Yom's wonderful art. However I will say that I can never like Yami the way her fans do (unless something REALLY drastic happens in the story).
Also, if do you want to know why I am more, let´s say, "tolerant" with Taa-kun, is because, as you probably know, he is securely the most decent and valiant male MC written by Maruto.
Believe me, Yuu is a saint compared with Tomoya from Saekano and Haruki from WA2 -my avatar-, who had all the defects and low self-esteem of Yuu... and much several defects more to add to the list. And much but more much lies and messings.
All these MCs has this point in common: they need his Angels go down from heaven to rescue them to be able to act. All these boys NEED these girls.
And this is important because is the real problem between Hikari and Yuu. This is the reason why she unawarely friendzoned him in middle school.
Hikari never was, is or will be the dommy assertive girlfriend Yuu so helplessly wants. Because she have never wanted to being it. She prefers being alone than to be the dominatrix of nobody. And that is fine, she is in her right. Exactly like Eriri with Tomoya, even if both Utaha and Megumi said to her, exactly like "Aya-chan" said it to Hikari.
This is the reason why Hikari never will be the only one girlfriend of Yuu. Her only chance is in the harem polyamory ending who Yami practically proposed in chapter 39 -and she would had a real opportunity to be heard by both Hikari and Yuu if she, again, would talked openly instead fall in her self-destructive menhera mode again-
