Excuse me, I'm coming in!
Good morning, Guest. He's so cute today too... He smiled... that smile is unfair... I want to pet him... I want to squeeze him... I wish Miu would step away for just a second... I could pamper him so much more if we were alone... I love him... I really love him... Calm down, I'm the older one here... ...I can't. I love him too much. I'm the only one whose heart is racing like this again today.
