@forecast That was a very well and succinct explanation along with
@kronix colorful addition about the boob loli.
Labris is a very interesting character since she has her own secrets, but she offers EVERYTHING SHE IS to Yuki. She did it with poise, grace and in the proper formula.
He has no choice but to accept her. This basically solidifies her social position in the hierarchy of the harem.
Even though he isn't boning them all, it IS a harem if the women around him will give it up any time his johnson gets hard.
FYI, this is my second or third time reading through this, and I'm just now understanding the plot. I blame the long time between updates too.
