When mom Aya Sakai uploaded photos of her adorable son Tasuku spending quality time with his French Bulldog Muu to Instagram, she thought she’d just be sharing them with a few people. But pretty soon, anyone with a beating heart and access to a smartphone discovered just how cute the inseparable friends are and the pics went viral.

With that, I give you Tasuku and Muu. Prepare for cuteness overload.
