Eeee Haru! <3

The concept of soft/petite and nice girls getting or being buff/over muscled is a wonderful concept. And you portray that really well while still maintaining the concept of the characters.

Very wonderful. Very good piece this one.

"Well, I have to admit, the muscles aren't natural."
"Noooooo really? I was sure we were both totally average body builders the size of houses who've never been to a gym."
"You don't have to be sarcastic about it."
"Look, if you're gonna hang out with me then mild acidity needs to be anticipated."

Oh they definitely go to the gym. >=3

They totally would. I think it is genuinely in character for them.

"Oh, is that too heavy for you, little guy?"
"Fuck...Hnnng... Off."
"But you're so small and delicate, you need a spotter?"
"Ma'am, I need to ask you to leave."
"Oh really? You gonna make me leave?"
"Everyone here is working hard to better themselves-"
"Uhhh..."
"-it's not okay for you to come down here and mock people because they're not as far along as you."
"I mean- I was just-"
"Do I need to call the cops?"
Later, outside.
"Hey, Haru, I got some ice cream, how'd the gym go?"
"Just- Agh, it's like you can't even revenge mock people anymore."
"Isn't living well the best revenge?"
"No, it really isn't... Gimme that cone, will ya?"
