"Kicking things off with boobs!"
Well, that's a way to start a chapter.
Whether it was a dream or real, she'd absolutely do that.
"You blocked the speakers in a ridiculous way!"
One, it doesn't block sound that well if you're that close, and two, vibrations are a thing.
"Haven't I gotten at least a little better...?"
"I burned it again!"

"Is it even safe to eat...?"
Unsafe bentos only happen in romcom mangas, so don't worry.
What she wears at the end is sexier than what she wears in the beginning.
It's always a tad weird when manga portrays cooking as some sort of mystical lost art that only a few chosen ones are capable of wielding.
Yeah, it's not that hard. You heat things up in a pan or in water until it gets the desired texture, and mix various things together after recipe. The end.
