I wasn't really a fan of Chimi here. I know we don't really see much of the two's perspective, but she really didn't seem like she was trying to get Eri to change her mind about the wedding, or didn't particularly seem to care too much either. I know it's to do with the whole calm and collected shtick but mehhh. It just rubbed me the wrong way.
Also not a fan of Chimi x school girl (damn totally forgotten her name), but then that's probably more me just not liking age-gap with school kids. Mehh. Was still an interesting take though, it's nice to see some variety in the yuris.
