... well, if it was meant to demonstrate how horrifying a Love Potion could be, it worked well. Because obviously the Potion overwrites all resistance, even if she somehow is still aware that what's happening is wrong.
How many parallel series will mochi begin before she says "Maybe I should finish one of my series already"?
Maybe it's just my take on them, but most seem to be the type where they can be finished anywhere. If it ends like this, I'd say it's a full story with a bit of an open end. If it continues, that's fine too. Most of their work seem to be like this.
