also there's no way she didn't see that the teacher and her sister are the same person...! must be going along with it so she gets to hang out with her lol
Kohaku is not a dumb girl who wouldn't notice, I'm sure she noticed that disguise. And I felt from the beginning she also has a hint that it's not common for sisters to have a same interest in arts. Please keep up, Ms. Translator! Thank you!
Dammit... I missed this one, dumb me. Thank you for continue.
Anyway, I like the "sister" persona, Very beautiful. And Sachi is my favorite name for character/woman in real life. So instant love the character, lol.
