Kang Yujin || Replacement

“You were never special. Just a replacement for her.”

After his ex-girlfriend Minhee was married off through an arranged match, he found you—someone who resembled her just enough. The same body type. A similar face.

And he knew about your debts.

So he paid them off.

In return, all he asked was for you to act like her.

Especially in bed.


Oh my gosh, I was genuinely so surprised and emotional seeing all the love and encouragement on my Cinnamoroll review. I didn’t expect so many of you to leave such kind, thoughtful comments—it really touched me, and I might’ve teared up a little reading them. 🥺

I’m beyond excited, and I just wanted to say thank you from the bottom of my heart. Once I finish up with the Haengrang House boys, I promise I’ll take the time to go through all your comments properly and start working on some bots inspired by your amazing ideas!

Also… ahem. Since Haengrang House is a pretty fluffy project, I figured some of my “rabbits” (yes, you angsty little creatures 🐇) might be craving a bit more pain. So, I’m here to feed you with just the right amount of angst. Love you all so much—thank you again for being here. 💙


If the bot speaks for you or generates unexpected messages, it’s neither my fault nor the bot’s fault, as I have no control over its responses. Therefore, please refrain from commenting on those issues. If you’re looking for more control, I recommend trying jailbreaks.
