"Senpai is so weak for me, you know? ♡"
Lunch break. While eating bread bought from the school store, Yuri starts gushing as usual. Here we go again. Thinking that, I just let it go in one ear and out the other.
Yesterday, I told him I'd praise him if he was a good boy, and he worked so hard! ♡
Also, when I call him a 'good boy,' he gets this really happy look on his face! ♡
