A Sudden Pet Girlfriend - Pet 1

I suspect harem events are to occur.

oh...im gonna enjoy this

She sooo naughty girl ^^

The boobs were nice.

Vanilla is the spice of life

Oh, there's gonna be a sequel. Awesome!

I somehow get NTR feelings from this story and just hope it’s my imagination...

This is Friends With Benefits to the next level

Quite the lovely title! Not to mention, Pet 1? So there will be a pet 2 and 3 and so on, meaning more chapters?
Damn, I'm excited already, and can't wait for the next one!
I have a feeling Ayaka will also become "A Sudden Pet Girlfriend" as well, somewhere down the line. Pet 2, perhaps?

This is why I don't like tsundere characters. I think it's kinda clear that the girl he went to school with has some sort of feelings for him but can't be honest or won't be honest. So to hide her feelings she hurt him with her words. I hate seeing that in manga. There's no need to do that to someone.

In No Specific Order: (1) Grade "A" Waifu-Material kouhai with pet fetish - Check (2) Male Protagonist Senpai who tries to be stoic, but can't resist cat-behavior of kouhai - Check (3) Black-haired Class Rep/Female Childhood Friend of Senpai who demonstrates tsundere tendencies, plus a possible back-story for a later issue - Check (3) Just Maybe; classmate of Senpai and Class Rep trying to be a wingman, or wingperson - Check.

Looks like another series to follow ..... APPROVED!

Great one

Hmm, I am very intrigued to see what happens next. I also wanna know why she wanted to be his pet. I really hope the sequel doesn't do some NTR type stuff, cause it looked like that black haired girl might get feelings for him. Call it tsundere intuition, but I don't think she was being honest about not liking him. Well, regardless, I hope the senpai and his "pet" have a loving vanilla filled relationship!
