It’s just two kids drawing, I don’t think we’re supposed to understand it
I believe its for who sleeps with whom on which day. E.g that column with all circles means they will all sleep together. The one with circles two triangles means the parent will sleep with one of the twins in one room and the others in another. The one with stars next to kids and daato means they sleep together alone.
That's my guess
Can someone explain to me about that chart? I don't understand it at all. http://www.mangago.me/read-manga/petit_mignon/uu/petit_mignon-chapter-1/10/
