It all makes sense now... And I feel like it's gonna get worse next chapter. This is so heartbreaking... Please please please, by the end of this Manwha let Jaehui get the help he desperately needs. And hopefully an education. This poor man.
Normal sex was permitted but he brought out the nipple clamps all on his own. Hope this makes the uke more open to actually trying what the seme wants without fucking with him too much (names escape me atm I'm sorry)
DON'T DO IT. I UNDERSTAND, BUT IDEUM SHOULDN'T GET PUNISHED FOR THIS. PLEASE JUST GO PUNCH YOUR BROTHER.
