I found something really interesting on myreadingmanga. It seems the story is not what it looks like. All those sex scenes weren't flashbacks, the master hasn't slept with all those guys and he didn't kiss his butler at the end.
The master (who is actually the SEME!!) and his butler are lovers. The butler took a nap and the master whispered in his ear a story as a prank because he is always too serious and wanted to see him a little messed up.
So all that happened was a dream, NOT reality, NOT a flashback. That's why when the butler woke up he asked the master if he did anything to him. He wasn't so close to him to kiss him but to whisper in his ear.
Plus, this is a one-shot, or more likely an extra because the original story is this https://www.mangaupdates.com/series.html?id=114864

Ha hah!! That Naruto moment!! (● ̄(エ) ̄●)
I don't remember the last time I read something so captivating. I mean, I finished it in 2 days.
I felt like this manga was a huge puzzle and every mistery, every chapter and every character was an important piece from it.
I liked every character (though Mailer and Yaoding are exceptions). Of course Rayflo and Cherry were my favs, but 86 was sooo odd(and sometimes cute) that I think I started to like this kind of crazy character ╮( ̄▽ ̄)╭
The only thing I wished for was a kiss between the main couple.They have a lot of HOT moments but no kissing scene ( ̄へ ̄)Beside that, everything was perfect!!

Maybe it's just my yaoi-dar, but I knew from the very beginning that Tatsuichi will be an uke ╮( ̄▽ ̄)╭
