Can't read Chinese, but the original Japanese was:
"Ehehe, I know what was actually going on back then"
"You used to tease me because you liked me, right?"
"N-No I didn't!"
"I know you did, because Sana-chan told me about it after we graduated"
"You're blushing, that's hilarious"

Is there an uncensored version?

Feels more like a translation of a translation. The text does not match with the original Japanese text.

I'm sure it was probably drawn during the Covid-19 period. It's been 5+ months now, plenty of time for drawing.

There seems to be more semi rewrite english translations now. What good is translating works if they're going to end up as rewrites?
