This was cute but I really wanted her first time to be with the person she actually has feelings for.. Oh well this manga is clearly just gonna be a giant ball of angst and drama and every chapter is gonna just try to up the angsty counter every time.
Their were already four people supposed to be involved here from the cover art now theirs a fifth? It's a bit much tbh.
On the cover, we don't actually see any detail of the person to the right of our main girl. It could very well be that the hand caressing her hair are all of the girls who are not Sui. It's possible Ms. Pharmacist is no longer relevant to the story, and that her purpose was served.
I'd rather she remain relevant, though. I like her.
