Yeahhhh Koyuki! Why not just tell Konatsu about your warm feelings for her? ( ͡° ͜ʖ ͡°)
I love how Koyuki's mum was basically giving Koyuki advice based on her own relationship with her husband (Koyuki's dad). Like just think... if she was giving advice based on that of a married couple, then that's pretty telling to me. As in, 'Koyuki and Konatsu are gay AF' - telling.
Also, you're not going crazy @Gibfady I agree that there's plenty of romantic signs going on there! And yeah it's sad that the 2 MC's aren't even considering that they have hella gay feelings towards each other, whether it's due to obliviousness or denial.
