Wanting to try a something, a fashion or style in this case, and not doing so because you feel it wouldn't be a good fit for you, fear of judgment from other people, not having the resources and means for it, being such an outlier from the general audience that they barely make the thing for people like you, or simply your current situation not allowing you the freedom to do so.
That's kind of a big mood right there.
I want the mums to get together. If they did, Runa and Iori would be sisters, and sister yuri is hot.
Matsuba should also be fine with two mommies.
Thank you as always for the scanlation.
