Omg I've been obsessed reading this! I really like it so far! It's so refreshing to see them being complete friends and then Adrien gets jealous... Bc he totally is! And Mari and Kim are pretty cute! I totally can't wait for more!
Just some things I want to point out. There's a part where they talk about middle names and Marinette says something about a shared heritage. Sure, Kim and Mari are both Asian, but she's Chinese and he is Vietnamese. Similar in roots but shared heritage...
Eh..
There are also a lot of minor spelling errors throughout the chapter. Things such as using the wrong your/you're, or"definately" instead of "definitely." I would suggest using a spell checker to edit your chapter before publishing. Other than that, this is really great so far!
