Apparently he acquired the goods (uniform) from someone with matching interests.

What if?

A «necktie girl» who makes them squee.

Yo!

Since he’s (supposed to be) a guy, he has no sense of distance with boys.

This uniform smells nice...

Oh my~♡

Kyaaa~

This is good! Great! Amazing!

Mahiro-chan from an alternate timeline where he (she?) refused to become feminine. After declaring «I will never turn into a girl!» and desperately resisting, he became even more masculine mentally than before his transformation. The fear of falling and defiance have caused him to grow even stronger and manlier. He considered refusing the drug and turning back into a man, but then thought about things like his friends’ reactions and having to go job hunting, chickened out and gave up on the idea. By the way, this Mahiro-chan holds the #1 spot for «most ideal boyfriend» (according to all of the girls)...

Ooh...

I think girls should dress like boys...

and boys should dress like girls.

fwu-

It feels like the man inside me is disappearing...

ffy

She’s losing it...

I have... I have to do something!

U-fu-fu♪

A-ha-ha♪

I, I won’t be myself anymore...!

If I’m gonna be a guy, I’ve got to look like one!

Appearance is everything.

Yep, yep!♡ You’re so cu... So cool!♡
