Hi, thanks for your feedback! 😃
I can understand that it feels a bit "forced" or badly written in some places but allow me to explain briefly how I interpret some of these things.
-I'll summarize one question as, "Why doesn't the MC just tell the girls that he needs the milk to end the curse?
---> None of the girls really kept the milk, but always dumped it down the drain. (or let the MC drink it directly out of pleasure ). Therefore, so my explanation, the MC would have to ask the girls directly to collect and give him the milk, which is very strange/perverted without context. I certainly didn't make that clear enough, but I figured the MC feared coming across that way. To mention the succubi and the magic is also out of the question for him. By episode 5, the girls are also not sensitized enough to "milking" as a way to gain milk (except Jane, maybe). They see it as pleasurable but not worth keeping. As if one would keep sperm or something. It is only at the end that the idea slowly arises to see the "mother's milk" also as "milk". Therefore, it is difficult first to simply collect the milk.
-Why did he bring the farm milk to the bar?
--> The MC actually wanted to donate the milk to the cafe, but Mirai didn't accept it and ordered him to take it back. I realize that he could have just taken it home first, but I explained it to myself that he just didn't feel like carrying it any further and wanted to meet up with the others at the bar. (He also goes together with either Kumi and Mirai, which also keeps him from going home first). I admit that, rationally speaking, this is not the best decision.
-He even wasn't suprised it (the milk) was gone, like he knew it would have happened.
--> In an optional conversation with Kiara, they briefly discuss the fact that the milk jugs are gone and assume that an employee of the bar poured it away.
Hope I could express myself understandably. 😅 To lead a little deeper disscussion in english is not easy for me. As I said, I understand your points and I don't necessarily want to revise them, I just want to show how my interpretation goes.
Thanks for reading in any case!
