So apparently this series got a prequel that follows Bun-chan's story when she was younger. As of right now there don't seem to be any chapters for it posted on Mangadex, but the page is new so I imagine that'll probably change soon.

Wow. Thanks!

SO CUTE!

ew, they're adorable

I'm crying... That was so beautiful and cute.

HELL YEAH

I crode so hard. Mii-chan's fears hit close to home. It was lovely that Hinako-chan was ready to help her through it. ;_;
