I think that this is really offensive. I'm sure you'll laugh at somebody being "sensitive" or something, but this needs to be said.
First off, yeah, the source material is all about the goofs of a girl being mistaken for a guy. So of course media derived from it would be a little transphobic, except the way you approach it is just,, disgusting.
Calling someone an "it" because you can't discern gender is wrong. Seeing through a "cross-dresser" isn't great, it's harmful to people who identify differently. Twitching at the sight of a dude wearing a dress? Wtf it's not unusual, especially when Harry came from the wizarding world where everyone made weird fashion choices.
Also, using Harry as this "holier than though" figure is not fun to read. I think hating interactions with the Host Club, constantly having enormous wealth and magic to solve every problem, and dismissing all of the wizarding world as terrible is frankly poor character development.

Ha, I had a brain fart where my eyes registered 'Independent!Brooding!Isolationist!Harry' as 'Independent!Brooding!Pianist!Harry'.
Thought it was funny and decided to share.

Cool

Got bored for a sec and figured out the standard form of the problem mentioned in this chapter.

This was amazing, I hope you feel proud of it because you deserve to be. 3

Definitely not awful:) Like it a lot!

I almost forgot Celsius existed!

I actually quite like this. The pace you went at wasn’t too slow, I read a story where it wasn’t until the 50th or so chapter until the main character finally got more into the romance side, which was frustrating for me and in the end I even ended up skipping around. But the pace you went at was good, and Harry’s obliviousness to his feelings wasn’t so obvious that I just wanted to bash his head in to get him to understand, for most author’s it ends up being that way. Also, you didn’t actually take too long, you focused on other things and let the romance slip in tiny pieces at a time, so that not all that I was focusing on was the pairing. Am I making any sense? I don’t think I am, but just be aware, that I think you did great, a lot better than even my favorite authors.

thankyou for getting them to know each other before the romance became even a idea

oh poor harry XD

Love BS. My dad doesn’t play with me anymore since I always win.

OH SO NOW THEY REALISE THAT THEY DO WEIRD STUFF!

This keeps dragging on without development, please tell me it we see something interesting (not annoying, like a bloody defenceless Harry being attacked) happen. (Isn’t it annoying when a bracketed portion interrupts the flow of a sentence?)

Ugh... I’m liking the fiction, though you keep saying Harry likes the hosts and stuff, though there’s like only one or two interactions where he seems happy around them, I don’t know, it just feels like you’re telling us something that isn’t actually shown

OMG I did not read the title of this chapter and only noticed something when I wanted to click on "next". For a minute I wondered whether Ron finally had managed to get some compulsion potions or spells on Harry and how he managed that - and how Takashi could not have noticed. Gave me a fright!
Oh well, on to the real one...
