I think it's "Itsumo osewa ni natte orimasu". Which means something like "I'm always in your care".
I bet it's more readable in katakana/kanji
I believe from my limited playtime that there's at least one non-NTR playthrough. I only played through two of the endings though and got utterly bored.
*edit* - this also depends on if you view the side-chicks as 'love interests'. They did not interact in that fashion with the MC during my playthroughs.
First of all, thanks for the answer.
I don't mind having to choose between two girls or more girls as long as i can save one. (even if you have assigned girl here if i understand well)
For exemple most of the recent game made by kegani laboratory have NTR and allow you to choose between one of the two girls (and sometime you can even save the two if you are really good).
Yeah i prefer if i can save more girl but if not, it can give tension or a certain urge to save the one i really want. Like you see (and probably enjoy) what happen to the other girl but you wanna avoid that to the one you are trying to save, amazing system.
Having said that, the gameplay of this game look boring, i will try it when i will have time but i'm not sure i will like it despite loving the chara design of the main girl. The combo of her long red hair + stockings work well with me, but to each their own : )
