The amount of hints in this first chapter are almost overwhelming ^^
But oh well, if Mr.-aspiring-nursery-teacher should plan "hou, let's rape the cruel yakuza-scum who's supposedly involved in my parents death"...he'll be in for a surprise.
Which is arguably a strange setting, but nonetheless in the realm of yaoi-possiblities.

Whilst reading (confused, but that's my own problem - I can confuse myself out of nowhere, no external influence needed) I was hit by the notion I was reading the yaoi version of Yoroshiku Master
( see http://www.mangago.zone/read-manga/yoroshiku_master/ )
and my stomach kind of flip-flopped all of a sudden.
That said, I finished the chapters with the (misplaced) disappointment of:
"No leash...?" (*-*)

Naoto, the little yaoi-fairy-embodiment of any supportive brother ever.
"I can't watch this anymore, I'm gonna make you make up"
But this slightly out-of-it grown-up...
"Alright, this could be:
1. a ghost
2. the younger brother of my runaway lover
3. some stranger with the same face.
...
Nevermind, just sleep in the next room."
Ch. 7 pg 14:
I produced the weirdest noise just now, for I tried to muffle my explosive laughter and it felt like the supressed air found it's way out of my ears or something. At least no one woke up.
