Simple story, slutty girls (may too slutty) but only with MC and the other girls, good animations, no endless grinding, clear choices...it's a great work. Updates are regular. Almost sad the story is close to the end...eager to see what the next project will be.
If changing relation between Iris and MC it leads to early ending. I thing the lines 988 to 911 need an ident (rest of story after the condition about Irisstatus is only abailable if she is the sister).
