Oh wow. I'm happy to read there is a story about kan-chan.. Coz even though he had an abusive relationship with yumi. He was strong and honest enough that there is something wrong with him. Admitting that can be a lot andvrhe trauma feom the prev relationship isn't on yumi alone .. It's clear that he also regrets what happened and is afraid of what he will do once he dates again.. I'm glad yumi found his true love but more than happy to know that kan-chan will also have. A story to redeem himself from yhe prev story.. :D
I was holding my breath all throughout the chapters and thinking of what will happen. next. Although i felt bad about someone else being his first i felt better knowing he isnt allowed to sleep with anyone else aside from the owner .. Hmm Subliminal message, i see. For me the ending is just right if it needs to be longer then more hot scenes please.
I think that the story has all the right ingredients to extend the chapters but then it will be a gamble either it will be yoo draggy or totally sexy. Anyways, having it as a oneshot is a lot better because of the twist even if it felt kinda rush.
