[Love Cheek] Cute Beast-kun *Started a Romantic Relationship with a Foreign Boyfriend*

“It’s my first time and I… I’m going to be fucked like this…!?”
She is a shy and quiet chick.
Today was her first debut at a Goods Circle event!
A big, shiny foreigner named Nicholas appeared in front of her!
It's kind of hot that a tall, good-looking guy likes cute things...!
While they hit it off and spend time together, she uses her natural talent to provoke Nicholas!
Nico-kun is supposed to be cute...! ! Unable to bear it, he suddenly transforms into a beast!?

Otome/female doujins are interesting, especially because they generally are more heavy on the "story" aspect than male works. Not to say that there aren't great story-focused male doujins, but they are a little more rare.

I quite like this one, not only is it cute but its also one of the few White Male Asian Female doujins I know of, and its vanilla to boot!
I only know of one other vanilla WMAF doujin, and a few netorare ones. Which is a pity, as I like the premise.
I will buy and post the rest of this series eventually, just gotta finish uploading a load of other works I have in my possession first.

Come to think of it, maybe "Foreigner" should be a tag here on this site. Would make finding the ones with that story aspect, be it male or female, easier.

The Female Lead's design in this one is very attractive, especially that airstyle.
