There are no half siblings here, only two twin sisters, and the blue hair dude is NOT related to the mc either by blood or by upbringing (he only shares some years of "upbringing" with the mc's sister -- NOT with the mc herself -- because he lived a few years under the same roof as another foster kid of the sister's adoptive dad, but he wasn't even officially adopted by the dad, so he was at most her sister's co-foster kid: barely even her sister's foster brother)
Hi just read 64 chapters in one sitting, and agree w the 1st reply they ain't siblings.
Thanks for precising because he looked like the dad of the twin sisters that's why I asking
I get what u mean the dynamic took me a hot 5 seconds to fully understand
Sooo, at first I was okay with them too, I could feel that they were feelings but now that they are brother and sisters I am like who is her half sibling mother I have so much questions...
