For those who are a bit confused:
Takagi Shigeyoshi (Shoujo mangaka) is doing yaoi under the alias "Ogawa Chise" and MORIE Satoshi is her twin sister.

Pen names arent explicitly intended to hide the person's identity. It happens often in cases where an author wants to produce a different genre/topic in their work; using their own name (aka the one they originally write with) could cause readers to incorrectky associate the usual theme with their new work. And so you'd get people viewing the work with preconceived notions the author may not want them to have. Essentially, it's a way to put distance between distinct bodies of work by the same author. Does that make sense?

This explain a lottare of thing

I think this was the Irihi no Umi Camelia and in flower language it means something like "Burning love"
Thank you I was looking for this ! ヾ(☆▽☆)
What a lovely coincidence if it was! Irihi-no-umi camelia flower during autumn though :( the ending was set in June.
Yeah I learn that after putting this comment... Let's just say it is because of the coincidence for now XD
Glad I could help :)
