I think there's a typo on P14;
So I feel a kind of affinity towards you...
Claiming to not be jealous of Atsuko and then subsequently suggesting a kiss that wouldn't be had with a best friend is pretty
odd behaviour. One might even call it revealing, perhaps.
I thought Kuroiwa was introduced to become a rival, also vying for Chiaki's affection, but didn't count on another layer of tension being stacked on top of it, in her relationship with Mashiro. It'll be fun to see that all play out, heh
Atsuko is such a good egg though; we might have to induct her into hall of yuri supporting characters deserving of a happy ending...
Thanks for the translation :>
