I still don't get the premise of the series as "NTR" considering that, as a harem protagonist, the dude will inevitably "cheat" on the tomboy anyway since it's not an equal poly relationship even if they ended up together (and IS in the middle of wooing other girls whenever we see him). Not even the author likes him as said in his commentary.
Not to mention, they AREN'T in a relationship in the first place, the only thing that resembles NTR is that she has a crush on the generic protag and is his childhood friend (which means they're designated to be lovers in anime-land, Westermarck Effect be damned).
So... why hasn't the blond MC's relationship advanced with the tomboy yet? As a genuine couple, that is, than to be continuously framed as NTR. We don't even hear his or her monologue outside of being more kissy during sex, not even one-sided on his part considering he literally mentions that he has a crush on HER in the first book.
tldr; I WANT THE TWO TO BE MORE LOVEY-DOVEY AS A FUCK YOU TO THE PROTAG DAMMIT
This is now my go to series/stories for when I have to explain to some 'gooners' the differences between NTR and Cheating.
I like how Daiki is being blatantly obvious to Saki that he truly loves her. Saki has to eventually learn the hard way that Makoto will probably never be proactive with her in 'his harem". It has nothing to her being coded as a 'losing heroine'. Sadly, it's just he possibly doesn't see her as a girl, let alone a woman. I mean he has to be blind to not see that.
Yet, thankfully Sambalteracy has already shown us the path to Saki's happiness. With Daiki, who may be a horny and passionate guy. Yet he has shown more love and care to Saki in these 4 issues, than Makoto has shown the other girls combined.
Speaking of which, where were the other girls besides the alien girl? Think that they too are being 'stolen' by better guys? Either way, I look forward to Issue 5 and possibly more.
