I couldn't really care for the new couples in this, not sure why
Which couples? AkiShiho are the most interesting to me because I like their history and I'm a sucker for their dynamic. I also really like YoriHima to a lesser extent.
I'm not as invested in Mari/Kaori and Haji/Momo. Maybe it'll change once their stories are developed more. No hate towards them at all, but they're not as interesting at the moment. But I'm open to reading more about them.
Aya/Miki are a pass for me. Aya has some redeeming features in being so open minded and supportive of Miki, but Miki's character is such a turn off that I'm deeming Aya a weirdo by association lol.
