I haven't had a good night's sleep since March, and before that I can't remember.
Seeing 2D characters sleep well gives me mixed feelings of happiness and sadness.
I hope the to see Ren and Mary exchange more words soon.
You see a lot of female childhood friends calling their male counterparts "-chan", too. Like Kou-chan or something...especially if they're still very close. If they've grown apart a little then she'll usually switch to the "-kun" like normal.
