Next chapter will be slightly delayed as I'll be going back to translate ch1 as well. Nothing against the other TL, I just like to have consistency.
We are currently 7 chapters behind; chapters release in halves every 2 weeks. I plan to wait and bundle them.
Anyway Kasumi a cute. The first chapter didn't hint so much but there's a bit of darkness to this one.
Not as much as
Dominant - that one's very toxic and bittersweet. But you're in for some melancholic angst regardless.
You'd be tempted to think Kasumi's "shame" is tied to more romantic desires, but it really seems to be the simple act of digging into Onee-sama's identity. She's desperate for closeness but terrified of betraying Onee-sama's trust. Yet clearly she subconsciously doubts Onee-sama too, despite herself. There's something this ties into later which isn't fully explained yet, but safe to say Kasumi's got issues.
There's also a nice contrast with Kasumi's reactionary self-loathing crashing into worrying what Momo would think if she undid the braids. Kasumi is a very selfless person, but selfless to the point it's only causing her pain. This manga is filled with lots of great little interplays or contradictions like that.
Momo's just a chill guy.
