The cover photo is not mine it is @fujiotte from twitter :3 Im so sorry if the story plot lacks so much. This is my very first time using and writing Wattpad. This is an AU of Hakukoyu. The genre is romance and fiction. By the way sorry for the cringe title, im a little uncreative when it comes to titles xD. I hope you enjoy!!

Koyuki and Hakuji shared their first kiss, and ever since they can't get their hands off of each other. Touchy baths, cuddling at night when they should be sleeping, "sharing food", the list goes on. What they really want though, is more. They can't take the tension anymore, so why not release it? WARNING: 🔞CONTAINS GRAPHIC SEXUAL CONTENT🔞. Don't like, don't read!
